High score: 47 ( EDIT: 56 :) )
Pretty good gameplay loop, loved the music as well.
The sound effects were a bit too high compared to the music, especially the "being hurt" sound.
The controls screen is disappearing really fast, first run I didn't know I could attack^^ it was a bit... overwhelming but then I replayed and it really clicked. Loved it. The art is nice, the gameplay is great even if I'd loved to be able to change direction midair, but was part of the challenge.
Really loved the difficulty calibration, it's tough but you learn and you want to play again, optimizing the routes etc. Great stuff!
