Very cool idea. The custom song importing is a really nice addition. The included music track is fun, and I loved the voice line when starting. It gave me that old arcade rhythm game feeling and reminded me of my DDR days lol.
I liked the art a lot too, especially the background. There were some really nice layering going on, and it felt very dynamic with the clouds moving and the grass swaying/dancing. The main character having their own little dance was fun too.
The umbrella mechanic is a nice addition to the gameplay. It breaks up the usual jumping/dodge gameplay and adds a bit of risk/reward with the slipperier movement. Really fun idea here, cool entry!
