Cool game and the mechanic is interesting! It was very nice to be able to play with a controller.
Few problems I encountered: on firefox, the input latency was horrendous. Hopefully this was resolved with the desktop build. Also, playing on an ultrawide, the background doesn’t scale while the rest does, so it was a bit weird, but nothing gamebreaking! Finally, I took so long to kill the boss that I heard the boos music was not looping ^^
Overall a very nice game, well polished and fitting the theme perfectly.
