Best game i have played on this jam so far. Love the graphics, the narrator and the quadropus sound. And i specially like how did you handle anti-frustration, with good checkpoints , quick recovery from death and easy way to reset puzzles.
Although i love the jump mechanic, i had some problems while moving right and left, that was a bit hard fo 'finetune' for a hard platformer.
And now, regarding to @Bread comment about not able to finish the 3 elevators puzzle because of quadropus glitching, i had the same problem playing on linux+firefox and i had EXACTLY the same problem on my platform game (i think you played it). My player was going trought platforms that move upwards and dying. Playing on win+chrome run your game and my game perfect with no issues.
So i will investigate more about it and ask on discord if this is known issue of the engine.
