I really dig the use of the theme in this one. The fidget spinner makes for an interesting weapon in a platformer. Especially with the almost metroidvania elements to this.
I feel like the mouse wheel controls are a little bit wonky. I like the idea (I have a pretty bad history of trying to make projects with weird controls because for some reason that scratches something in my brain), and eventually I was able to get used to it, but I don't know that they were too intuitive from the start.
All in all, simple, but really well executed and fun. Lovely art, cute little story, and a creative take on the theme. What more could I ask for? I could see this mechanic being expanded on as well!
