Really fun idea, I love these types of games where you build your own level. It's so fun to hit a trampoline while going really fast and just skip like half the level lol. I think it'd be cool if there was incentive to put in the more dangerous sections (maybe a point/money system or something). Otherwise I'd just love more wacky contraptions to play around with but what's here is a great scope for a jam. Awesome job!
