The animation is a sight to behold. The tutorial stage alone is great because of how original the theme is, and how cool it is to see pencils, erasers and protractors shape the level design! The gameplay itself is solid, with Sonic controlling very smoothly. My only criticism is that the main level becomes repetitive after a couple of minutes in, and I didn't feel like I was being challenged in any new ways afterwards. (More enemies and harmful obstacles might be the solution in that regard). Otherwise, really fun to try out, and I appreciate the visual humour included here and there...
