Hi,
the controls felt amazing, like I love them. The lo-fi music on the background wasn't really a fit for this type of game though, I think an 8-bit type of beat would've added a bit more to the aesthetic. The art or the game was simple, but perfect for a platformer (shiny things are good, spiky things are bad :)) and you just nailed it with the idea itself, which I have not seen before!
Keep up the good work!
