Nice work. I loved the snail timer. Very cute. And all the graphics and animations were great.
I did find falling to be really frustrating, but only because the movement was so slow that to get back to where you were just took a long time. I think the arrow growing a little faster would be nice, and maybe some way to just walk left and right instead of always having to jump. It made getting to the edge of a platform feel really slow.
Overall though, nice game jam entry. Good work.
