Thanks for taking the time to play it, and for the feedback!
I was actually planning to add some invisible blocking volumes below the platforms, so they would allow you to get onto it if you just missed it by a tiny bit, like Mario, but I was running out of the time at the end and I left it for after the jam is over.
I wish my level was a bit bigger, your game really impressed me with how much play area you managed to create :D.
Thanks!
