Really nice little game here! I loved the menu and death music, very bouncy and silly. The UI on the menu could be implemented a bit better as I could barely see the controls and credits button. Also, may as well throw the menu music in the credits and controls screen as well. The addition of a quit button is also a nice quick quality-of-life thing to add.
I see people complaining about the controls midair, but I actually enjoyed it! Although unnatural compared to what most of us are used to, I think it perfectly adds to the difficulty of the game!
Also, as Mister Salty mentioned, random generation is essentially a must for this game since once the player gets to the bottom there's nothing else to experience.
I enjoyed the graphics and the animations that the player character had :)
Overall really fun game, just a few QOL adjustments and the addition of random generation.
