Very interesting concept! I'm a big fan of the artstyle! However I'm sure you are aware how unfinished the game is! Really feels like its missing some sound effects and music, there were some camera issues in the lowermost room, the jump feels like there is a bit too much gravity applied when falling but otherwise it feels nice!
I'm personally not a fan of having to use a controller like you mentioned on the itch page, wish there was proper keyboard support as well which is probably 80 % of people playing games in this jam but overall it has a lot of potential so I'm really looking forward to future updates if you plan to continue on making the game!
