Okay so this is just the Drunking of Isaac. Got it. Jokes aside, I am a great fan of the Binding of Issac so this is just the game for me. I think I've even recognised some of the room layout too, but that might just be a coincidence. The game is quite hard, and I can't state enough that not being able to walk straight makes dodging enemies and bullets much difficult than normal. It's fun though. The neon colour theme looks nice and makes a unique vibe, and it stands out quite a lot. I will also praise you for putting in the effort to make a bunch of powerups for the treasure room.
For some criticism, I'd say its a shame the floor layout doesn't change for different playthroughs, but I guess that's too much to ask for, given you've just got a week to implement all this stuff. I would also hope that there is another powerup at the end of each level. That would make each run more unique. It will definitely need more powerups though, so that might be another too much to ask for.
Anway with all that's said, this is a very nice game, and I liked it a lot! Well done!
