This game is actually great!
The gunplay is dynamic, the reloading animation is really satisfying, the music and visuals are cohesive and the controls are simple but effective!
But in my opinion placing the jester as the first boss isn't.. great: the other two bosses mesh really well with the gunplay, the dash mechanic and the healing system but the jester can 2-shot you, is impossible to hit with the shotgun or smg, and the platforming is really difficult to learn and he crashed the game 3 times.
Overall great game!
