''Slime Forest Adventure'', or "Project LRNJ," is a [[{{Retraux}} retro-style]] [[RolePlayingGame RPG]] for [[PCVsConsole PCs]]. To win, you must learn the [[JapaneseLanguage Japanese language]]. Not your character; you, the player.

Enemies attack by throwing Japanese at you. You have to respond by typing the correct meaning or pronunciation (whichever is asked for). If you make a mistake, you lose [[HitPoints health]], after which the correct answer (usually with a mnemonic) will be displayed.

You can download the free demo and buy the full version from the [[http://lrnj.com/ Project LRNJ website]].

!!Contains examples of:

* ThreeQuartersView: Everything except the combat screen.
* AllJustADream: [[SchrodingersGun If you die]], it will turn out that you dreamed everything that happened since you "woke up" that morning. [[OrWasItADream You'll still be very low on health, though]].
* AntiPoopSocking: Studying ''anything'' is best done in short, frequent sessions. You learn faster, and retain the knowledge longer. This game has several features to encourage you to do this:
** You can fully restore your health by eating a meal in your home. You only get three meals per (real time) day.
** Sleeping in a bed [[SavePoint saves]] and exits the game. It will also restore your health if you wait long enough before continuing.
** [[PlayEveryDay If you wait too long before playing again]], the inn will charge you extra for overstaying.
* BrokenBridge: {{NPC}}s in inconvenient spots block off most of the castle.
* CharacterLevel: There is a rudimentary level system in place, included mostly because it's simply expected of an [[RolePlayingGame RPG]]. The ''real'' leveling that takes place is in the player learning more Japanese.
* ColorCodedForYourConvenience:
** Green slimes teach kanji meanings (usually; sometimes the identifiers aren't strictly a valid translation)
** Bright blue slimes teach katakana.
** Red slimes teach hiragana[[labelnote:*]]Unless you are playing one of the kanji-first modes, in which case, [[ThreateningShark sharks]] teach hiragana[[/labelnote]].
** White slimes teach romaji pronunciation.
** Dull blue slimes teach kanji [[AlternateCharacterReading on'yomi]] readings.
** There are actually a few enemies that ''aren't'' just [[PaletteSwap palette swapped]] slimes, such as the whales that teach kanji [[AlternateCharacterReading kun'yomi]] readings.
* CriticalExistenceFailure: Again, as a {{Retraux}} {{RPG}}, this is a given for both the hero and enemies.
* DiscOneNuke: The game becomes really easy if you [[spoiler:already know Japanese]].
* EdutainmentGame: Its explicit purpose is to teach you Japanese. What did you expect?
* EscapeRope: The "Escape Twine" returns you to the surface from anywhere in any dungeon.
* EveryoneCallsHimBarkeep: The Pirate.
* ExcusePlot: It's something about a potato farmer and a kidnapped princess, but really, if you're playing this game for any reason other than learning Japanese, you're doing it wrong. (A [[WordOfGod stated goal of the developer]] is to eventually make the game fun for anyone, even those with no interest in Japanese. But it still has a way to go in that regard.)
* FauxlosophicNarration: Only once. In the first level of the first dungeon, when opening one particular [[InexplicableTreasureChest chest]], the text reads, "Fortune smiles upon thee, and laughs at something that's not really funny. Thou hast found the [[HealingHerb herb]]!"
* FightWoosh: A closeup of a slime momentarily blocks the screen. When it moves, there's the fight screen.
* GetOnTheBoat: After you buy it from [[spoiler:The Pirate]].
* GraphicsInducedSuperDeformed: Just look at the page image.
* GuideDangIt: The entire "Mine the Hills for Minerals" quest:
** First, you first have to find all the tools yourself, one of which is very well hidden, with no clues.
** Using a tool while standing on a hill tile results in a generic "Nothing found" message. You have to be standing on another type of tile, ''facing'' the hill you want to mine, to be able to successfully use the tool.[[note]]This has to do with the game mechanics. It's been repeatedly established that there are no enemies of any sort in the hills. But combat is the way the game trains the player, and without training, the mining quest would just be [[ItemFarming pointless busywork]]. So, by forcing the player to stand on another type of tile, the game can believably trigger a random encounter for each mining attempt, which you have to win in order to get your rock. It's just too bad the game never tells you this.[[/note]]
** You have to give all the needed rocks to the smith at the same time. If you just give him one rock, he will complement you on it, which makes you think that you're making progress, but what actually happened is that you just lost that rock for no gain.
* HealingHerb: The [[ExactlyWhatItSaysOnTheTin Herb]].
* ImprobableWeaponUser: You start the adventure [[WithThisHerring with a hoe]] as your only weapon.
* InexplicableTreasureChests: All over the place. In fact, with the exception of stores and a mining mechanic (that's only used once in the whole game), chests are the only way to get items.
* KleptomaniacHero: There's a woman in one home who [[TalkToEveryone will tell you]] that she has just enough money to feed her six children for the winter. If you open the [[InexplicableTreasureChests chest]] next to her, [[FridgeHorror you get 200 gold from it]].
* LevelGrinding: Complete with a "Summon Monster" item, so you don't have to wait for random encounters.
* MoneySpider: Justified, the slimes are attracted to gold. It's why they attack you, and why the local economy is going down the drain. The gold you get for killing them is just the gold they took from someone else. Somewhat less justified with the [[EverythingsEvenWorseWithSharks sharks]] and whales.
* MonstersEverywhere: Well, except for the hills.
* NoHeroDiscount:
** [[AvertedTrope Averted]] in an interesting way. You're not actually a hero, you're a potato farmer, so there's no real reason for anyone to give you a discount.
** [[InvertedTrope Inverted]] by the king. If you bring him some evidence that you've actually got a shot at [[SaveThePrincess rescuing his daughter]], he'll just ''give'' you an [[AnAxeToGrind axe]] to replace the [[ImprobableWeaponUser hoe]] that you've been using.
* NPCRoadblock: A few appear in the castle, some of which are mobile but will never leave the single-width corridor.
* ObviousBeta: It's in continuous development. Because of the game's unfinished nature, if you buy the game, you get free updates for life.
* OnlySmartPeopleMayPass: It's the whole point of the game.
* PaletteSwap: See ColorCodedForYourConvenience.
* PlayEveryDay: See the entry for AntiPoopSocking, above.
* SaveThePrincess: After which, [[spoiler:you become a member of the royal guard, which opens up more of the castle to you, and gives you the opportunity for more quests.]]
* SavePoint: Beds. [[CaptainObvious Inns will charge you for the use of their beds]]. Other beds (such as the one at your house) are free, but while you sleep, slimes will steal more than what the inn would have charged.
* SelfMadeOrphan: [[spoiler:The Pirate's father killed his mother, so he stole his father's pistol and "[[DeadlyEuphemism sent him to apologize]]."]]
* ShoutOut: The kanji 奇, meaning "[[http://jisho.org/kanji/details/%E5%A5%87 bizarre]]", is written with the radicals "[[http://jisho.org/kanji/details/%E5%A4%A7 big]]" (大) and "[[http://jisho.org/kanji/details/%E5%8F%AF able]]" (可). The hint given for it: "'[[WesternAnimation/TheSimpsons Embiggenable]]' is a ''bizarre'' word".
* TakeYourTime: There's no concept of time passing in this game. At all.
* TalkLikeAPirate: [[CaptainObvious The Pirate]].
* TalkToEveryone: Again, {{Retraux}} {{RPG}}.
* ThereAreNoTents: And the inns are also [[SavePoint save points]].
* ThrivingGhostTown: There isn't a town in the game with more than 20 individuals.
* TraumaInn: But only if [[AntiPoopSocking enough real time passes]] before you load the game again.
* VideoGameGeography: Hilariously [[LampshadeHanging lampshaded]] by the guy at the entrance to one town; he's trying to make a map of the world, and driving himself batty in the process.
* WalletOfHolding: You can carry up to 999,999 gold pieces with no restrictions whatsoever.
* WelcomeToCorneria: [[UpToEleven Oh, so very much]]. In fact, one castle guard says nothing but "Welcome to the Castle," which causes their friend to say [[LampshadeHanging "I think there's something seriously wrong with my partner."]]
* WithThisHerring: You start out with a hoe, and the clothes on your back.
* WrapAround: But only after you [[GetOnTheBoat get the boat]].
* YouALLLookFamiliar: There are maybe six different sprites for {{NPC}}s, total.
