My first thought: Wow, this is some nice, clean art. And your game keeps this impression till the end. The timing, and bouncing, dash and movement fell all just right. This all feels like Moonlighter, a game that I also really like to play.
Our games are kind of similar. Here your slimy hero is colorless and tries to get his color back. In our game, the fireflies lost thier color due to an infestation, you can help them to get it back. Would like to hear your oppionion on that.
