Great game! Nice twist on the old bullet hell standard. Quite challenging without being overly difficult; however, the final boss was a little unfair at times. There should be a tad more recovery time between bosses; there were times when I would get hit without any chance to dodge if the right enemy appeared at the wrong time. For instance, sometimes I would be at the bottom of the screen and the boss whose shots travel upwards from the bottom would appear and instantly fire, hitting me as soon as the previous boss had faded from the screen. Other times I would be close to the center and another boss would appear and hit me instantly, almost always the one who fires multiple lines of three shots directly at you, as his "face" is pretty far forward compared to most of the others and his shots move faster. If there were 2 or 3 seconds in between before the shooting started, it would give me time to register which enemy I was fighting and prepare accordingly.

You have to keep killing them until it stops saying "kill him" and the guys stop coming. Then the door you came in will open and you go through. A door that you passed further back will also have opened
