I've been following Pico 8 games for a while now, and I noticed that the genre that has the hardest time converting to Pico is platformers. That being said, this is definitely one of the better Pico platformers I've played! The controls are a little slippery, but for a Sonic parody, that's alright!
My biggest problem was the camera. When you went too fast, the camera would take a while to catch up, and it kinda made running fast more of a problem than a mechanic, yaknow?
It was also pretty dang short, but I personally enjoy short games.
