Great game! I think there was a decent amount of enemy variety for the time given, especially the one that blocks bullets, which increased the difficulty by quite a bit. I did, however, find that running back and forth while shooting constantly dealt with most of the enemies pretty easily, so maybe reducing the shooting speed or the size of the bullets/changing up enemy move patterns might help to alleviate that issue. I also liked the "daring" pop-up when enemies got close, and I think it would be neat to give the player a bonus of some sort when they pull it off. Overall, a pretty fun and engaging game.
