Hello, Hello. This is the Planet Genetos. Who are you?
Genetos is a freeware Shoot 'em Up game with an "evolution" theme. Each level mimics a different era, going from a Space Invaders homage through the nineties and up to Bullet Hell, and each has an associated ship, from a simple left-and-right-moving white blob to a sophisticated weapon of mass destruction with bombs and lasers. The game can be downloaded here.
Though bosses also start using new attack patterns when you evolve, meaning it is sometimes easier to fight them before evolving.
Cute 'em Up: The very first level. The rest of the game is more standard shooter fare.
Defeat Means Friendship: Sort of. If you get the Summon Subweapon, you'll be able to summon bosses you already defeated to help you.
DummiedOut/The Dev Team Thinks of Everything: if you were to examine the folder containing the game's music, you would notice that the songs Answer, Rebirth and Origin have both a midinote well, except for Rebirth version and a MP3 version. The Dev Team Thinks of Everything comes in when you try to rename the MP3's into the proper MP3 extention and open them. Not only will it play in the media, but those MP3's are actually fully tagged, as if the developer anticipates you doing that. Dummied Out also comes in when you had somehow successfully converted the midi files into the proper midi format note Those midi files are not in the standard midi format. In order to convert them in order to listen to those songs outside Genetos, one needs to find a extremely-hard-to-find-if-your-not-Japanese oreshiki decrypter.. You then get to hear what those songs would have apparently sound like before the dev decided to use MP3's for those songs instead in the final game.
Well, as the text that reads in the Final Generation plainly states, everything must come to an end. So the next generation is, possibly, just the inevitable following period of creation. After all, the hardest difficulty levelis called...
Infinity+1 Sword: Two highly damaging ones can be acquired. While they are tricky to aim initially (they open and close as you move) and start small they do very high damage and virtually fill the screen when used by higher level ships.
Interface Screw: The motion blur feature. Even its lowest setting will make your eyes hurt after extended exposure.
Laser Sword: Obtained if you play aggressively and get close to foes.
Level Up: Your ship isn't necessarily matched to your stage, instead improving when you collect enough of the green pellets dropped by enemies.
Self-Imposed Challenge: In Free Play mode, you can do things like trying to play the later stages with a Level 1 ship.
Certain evolutions will prompt you to defeat that generation's boss with that generation's ship. In some situations, this is easier said than done.
To elaborate, not only must you use a weaker ship to beat the boss, you must avoid collecting too many EXP power-ups during the boss itself, and all the bosses are Mook Makers. You could try to avoid the EXP in the stage and time it out, but that's a challenge in and of itself (especially with higher-leveled ships, which tend to attract EXP).
