330.69 seconds, 28 deaths. You made a good platformer sir. My hand hurts a bit :)
You did the difficulty curve perfectly! Thanks to adding each part gradually the player remains encouraged. I felt like "I already beat that part, so I need to go through the new stuff, and through the familiar stuff". Again- this is difficulty design that I'd appreciate in a "big" game!
Controls are vital in platformers. If for any second I'd felt that I landed in spikes because of floaty controls, and not my mistakes I wouldn't finish the game. Because I finished, you know the controls were TIGHT!
The graphics are minimalist, but in a cool way. You added some juice, by squishing the character, and I was a bit surprised when it turned out that the hitbox is squished too!
The sound was... ok? Sound effects worked ok, but the music stopped looping after a while. Not a huge problem, but something to fix.
Use of theme was on point. I loved how the obstacles "grew" filling the room.
Over all- great game. Normally I think making a difficult game for a jam is a gamble, but you pulled it off!
