The control of the character feels pretty sluggish as if driving a car on ice,which makes controlling the character unsatisfying.
Moreover,the movement speed of the character is pretty low(even with 3-5 movement upgrades and also while not shooting),making dodge roll the only reliable movement option.I would suggest at least make the character be able to move quickly when not firing the gun.
The Type-C gun suffers from this the most since it cannot charge while rolling,which combied with the naturally slow attack rate,makes the player very vulnerable when surrounded by horde.
the enemy projectiles being green also makes it blend in with the background which becomes hard to notice sometimes.
That said,the music is lively and the graphics are cute,and the Type-C gun is very cool despite being the weakest gun.
