Very nice little bullet hell like.
The controls where great, although the cooldown on the dash seemed a bit slow, even with the upgrade to it, but it wasn't necessary to finish the game.
The bullet patterns and attacks of the bosses where nice to get to learn and avoid, although, the big AOE explosion could use some better telegraphing, because it's sometimes blocked out by the player sprite, and is generally hard to tell the range of. Maybe a filled white circle indicating the damage zone.
All-in-all, had a fun time.
Would like to know more about the story and lore of the world, as well.
