I love the style of this game, it's nice and cohesive and fits for such a short time. I also really like how pretty much everything has a sound effect, it adds great juice.
I had some difficulty in the two sections below. The top picture these platforms are REALLY small and hard to land on. I found when I did manage to land on one, I'd accidentally run off when trying to jump to the next. I spent a good few minutes here. There is the cube that you can resize right below it, but I didn't figure out how to use it if that's the intended solution.
Bigger platforms would be good, but if you added in some coyote time for the jump I think I could have gotten through much quicker.
The second picture looks like a path, but right in front of me was an invisible collision.
This is a great showing for the jam though, really impressed!
