Love the concept, art and atmosphere! Sadly I really struggled with the controls, I just could not get past the 3rd room, the double jump was so challenging (or I totally missed something) so gave up after a few minutes. I’m not sure exactly how you implemented jump, but the way I do it is give an initial large velocity up on press but also reduce gravity while the player is holding jump until they hit the apex and start fall, then gravity is normal. If they release early, then the gravity applied is normal. Not that I’m saying this is the best way, but just an idea. And, like others, would love to see controller support. Keep it up!
