Spoiler Alert is a platforming game where you have to uncomplete the game. You start out beating the last boss, get the princess, the credits begin... and then the game reverses, and you have to unbeat the bosses, unkill the enemies, and uncollect the coins to find out how it started. And if you, say, kill something new on the way? You create a time paradox, and get thrown back to the beginning of the level. The levels are short though.
Spoiler Alert contains examples of:
- All There in the Manual: If you purchase the Steam edition, you get a 16-page comic book that explains what made Chili Pepper Knight set out on his quest.
- Already Done for You: Played With. All the killing and collecting have already been done... by yourself. You just replace and/or revive what was once gone.
- Anthropomorphic Food: Your character is a walking chili.
- Backtracking: Every world starts with the boss, and ends with the first level.
- Bonus Level: Once you complete the game, you gain access to a bonus world with 10 new levels.
- Context-Sensitive Button: Kinda. The Z-button moves you to the next level when you complete a stage, or retrieves whatever special ability you have equipped at the time (there are three in total - one for each world).
- Game Over: Averted. If you get a Time Paradox, you just restart the level. And you have an unlimited amount of retries.
- Goomba Stomp: How you unkill enemies. You get other abilities on occasion though.
- Hero Antagonist: The only reason Chili Pepper Knight went through all the trouble of kidnapping the princess was so he could move out of his house.
- Microtransactions: As an April Fool's joke.
- Now Do It Again Backwards: The premise of the game.
- Railroading: Combined with Ratchet Scrolling, since the game moves forward on its own. True to the reverse theme, you move to the left.
- Speed Run: A special option is unlocked once you complete the game, enabling you to compete against others on the leaderboards.
- Spikes of Doom: Both the traditional and the falling kind. note
