Bosses lack variety in their attack patterns. As for me, the first boss (Any boss) should not endlessly throw projectiles in different directions (Even Hush from isaac doesn’t do that). I liked the upgrade system. Everything is intuitive and interesting. It would be cool to have some kind of dodge, or a mega bomb that would destroy shots, like in the old games (This would solve the problem of the first boss). Overall the game is good, I liked it.
