Deja Boom

Deja Boom is a browser-based action platform game where every mistake becomes part of your progress. Instead of losing everything when you get hit, the game replays your previous moves through a “ghost version” of your character. Each time you respawn, that ghost repeats your exact actions from your last run, allowing you to team up with your past self. The more times you play, the more clones appear, giving you backup in tough fights and making strategy as important as reflexes. Players can try out Deja Boom for free on kbhgames.com, where it runs smoothly in the browser without needing installation. This mechanic turns trial and error into part of the challenge, encouraging players to experiment with different approaches and eventually push through levels with the help of their own growing squad of past attempts.
