The fast-paced platforming is both fun and simple enough for anyone to grasp, kinda like Mario or a classic Sega Genesis game I don't recall off the top of my head. 

Anyways, presentation is great. I can't speak on the music as I was the sole composer for it, so I think I'd be a bit too bias to it. Sprites tho, are really solid. The stages all pop with nice colors, the squash and stretch on the slime enemies is fitting and really smooth. Manuee's Idle animations are very charming. 

Level design has plenty of secrets to find, making collecting all 9 coins somewhat challenging and interesting to explore every wall. Solid time if you have 5 minutes to spare.
