Really fun game, it's awesome that you managed to add procedural generation to a game jam project. Honestly the difficulty could have been pushed even further, since reaching the victory screen was almost easier than reaching the death screen. I really like both ending screens, but maybe some of that time might have been spent making one or two additional enemy types to spice up the gameplay itself. Solid entry!
Also as a side note, the game window seems to be cut off on screens smaller than 1080p, and on my 1080p monitor I had to go into fullscreen (F11) to see the HP bar.
