The intro cutscene is kinda funny, but the rest of it before the boss is... pretty much just circle strafing around the same enemy type in very slightly increasing quantities on each new floor over and over again while button mashing...? I'd suggest adding a few more enemy types if you ever expand on this, preferably some with increasingly silly concepts. Also, a crosshair would make aiming easier.
Oh! And it is appreciated that you change up the music for the last few floors. Which I reached without taking any damage by the way.
Also, I actually reached the boss without taking a hit. Unfortunately, due to the mashing involved in the game, I was only really able to give the boss one real shot, in the interest of being able to potentially play any more games in the jam before time is up, but it's probably the best part of the game that I saw at least. No idea what the ending is, but I don't think it'd ultimately affect my score much, since most of my issue here is in the core gameplay.
It's... fine, I guess. Kinda.
Eh.
If you do improve it I'll be curious to see what it's like then more, admittedly. So at least there's that, you do have at least potentially have my attention for a future version of it.
