Cute! That was my first impression.
I struggled a bit at first with what exactly I was supposed to do but once I worked out the first shop didn't really matter (maybe I'm wrong?) and closing it starts a new level I was in the loop.
Maybe it was an issue with my brain, but at first the shop didn't work for me - I eventually figured out I could move around the shop with tab and buy with enter but something telling me that in the shop would have been super nice.
The gameplay is simple and fun and I like controlling the character, the only thing I would add is it can feel a bit unresponsive when trying to jump right after landing, not sure why.
