This is quite good! The color mixing is fun and the slider system is also great!
I also feel that the gameplay would lend itself nicely to some more gamemodes, but as it is right now it's still a solid time waster.
This is really good! The main gameplay loop is fun! I liked moving through the vault(?) and I liked how it's possible to see through the guards lights as well.
Something I do wish for however is the guards lights being different colors then the players light. (I also noticed a glitch where the death screen text would get blocked out by a light.)
Overall though great prototype! Would love to see it expanded at some point!
That was fun! At the end I thought I noticed a glitch that made the level impossible (at a checkpoint the clone would respawn at the beginning instead of where the checkpoint would be for the clone), but it seems like you accounted for that with a small gap!
(Maybe make the keys for restarting the game/game or changing levels different, as those keys aren't on all keyboards.)
the controls feel a bit stiff (you cant hold left or right), but other than that its quite fun and looks nice
you also really captured the feel of old tetris with no hold and completely random pieces (modern tetris has a "bag" system that goes through all 7 pieces before getting a new round of pieces (in case you didnt know))
