Shrek

The one before the last, it's intended.
The one with the buttons, the solution is to push between 1 and three 3 buttons and just wait a few seconds. Pushing 4 buttons is supposed to restart the room aka failure.
In the bottom left of the screen is a hint for each solution, but it doesn't scale with your screen size and can be easily missed unfortunately.
Nice concept and art. I like that you made weapons foe each world.
I don't know why so many unity and godot web fps games make my mouse automatically move if the game isn't in fullscreen. I have this issue in my own games as well. Appears to be a problem on my end probably. Anyway great job with your game!
Update:
Now it's playable. I ran into the issue that no more enemies spawned and I was seemingly locked in level 2 but the game cleary fits the theme and the core gameplay can be tested (and I could beat some nasty seat snatchers too). I'd add walls left and right of the arena.

I had the same experience as @yhpah. The character sprites look unique and interesting, the music sound fun but unfortunately it's unplayable due to the ui being cut off.
