Me and some of my friends played this the other day when we were doing a little SSJ game marathon, so I figured I'd come back and leave a comment haha
The art style is really cool! To go with the theme in the comments of comparing it to other things, one of us commented that the warped perspective in the rooms was kind of reminiscent of Courage the Cowardly Dog, which I can kind of see. Similarly I was getting a kind of 90s PC horror game vibe, I in particular like the main characters sprite.
I know you mentioned that you actually didn't get everything implemented, but I actually feel like you could have edited the scale down and it would have been fine. I feel like when some of the more intense monster designs started popping up is when I started getting more into the game, but that was a few rooms in. Those first few rooms felt maybe a bit repetitive, but it's hard to get pacing down obviously haha
(Also, after beating it, we went back to get the bad ending and got a kick out of the end screen. Something about the text and eyes just hit right)
