Awesome, at first I was a bit confused getting used to the game's controls but after that it was pretty fun to play.
The mix between sidescroller (with gravity that you have to keep in mind) and rhythm game was very interesting idea.
Moving & trying to dodge both the screen's bounds and the enemies were hard because of this dual-purpose nature of controls where you have to aim with mouse for both moving and shooting.
But if you get the hang of it then it turns into an interesting decision game where you have to either focus on dodging or dealing damage to the boss.
Meanwhile, I was able to occasionally go out of bounds and stay there without getting a game over.. Aside from issue like this, overally the game has interesting mechanics in it & it was a pretty solid and fun game to play.
