Great job! I loved the art and animation (that is an insane amount to do in 48 hours).
The music was fun and appropriate. I enjoyed the sound effects a little more though (having only 8-bit music felt a little overplayed after my 20th death. good pace though!)
I definitely sucked at it for a while, but as with most timing games, it got easier as I got used to it.
Overall, super fun and visually impressive game!
