The game had a decent look, but many collisions felt off, and sometimes, is_on_floor did not trigger, so a jump was not registered. Polishing the movement will assist.

Thank you for playing! This is our first time making a video game, and your feedback will help us make better ones in the future!
I think the jumping problem comes from the fact that the smaller platforms have diagonal collisions at the end, which I think might have been a mistake in restrospect, because the movement system can't be sure whether the player is on the ground or falling because of that 45 degree angle and settles with falling. I will remember that for next time!
