Super fun concept and I really like the power ups. Art is also really nice!
Not sure what the later levels are like but I think the first level might be a little too hard, I wasn't able to beat it. Partly because my fingers were cramping up close to the finish line but also because the optimal way to play (at least for me) seemed to be to use both hands so I could mash faster but that also meant I wasn't able to use the powerups.
