Overall great art! It's very aesthetically pleasing. Props to Christoph!
The cutscene at the start of the game was really cool.
The music is nice & fitting, although there are no transitions between tracks making you lose immersion when the music cuts.
The controls should have been explained in the game itself though (or on the itch page) - I totally overlooked the controls screen in the main menu, started playing immediately, and was stuck with only a dash & movement not knowing what to do.
But in general, congrats, nice work!
