Not very satisfied with the ending. Killed 1146 enemies (the final 600 or so were apparently invisible, somehow dying from a guitar riff after reaching a combo of 300-ish from the triangle), the exit door eventually opened, and I was left to wander a desolate wasteland until eventually reaching the end of the floor and falling into the void. Also, didn’t find any reasons to use the cymbals or the slide whistle (inconvenient locations on the controller, didn’t want to risk losing my combo). Also, might have been worth making the enemies a bit more fragile, seeing as there is an utterly ludicrous amount of them for the player to force their way though.
Still, got a solid concept here, even if the execution was a bit dodgy.
