I'll give the same criticism as I gave to Catlike Magic, as they're similar enough.
The visuals are pretty nice, I'll give you that, but the gameplay is slow, enemies have too much hp, most of the time you feel like you're just waiting for enemies to die. I'm not a fan of inertia in dodging games too.
Besides that, its very fun to experiment with gun modifications. I just wish the player default shot had a bit more impact and speed, in the beginning the player is faster than the shots.
