I quite enjoyed this. The screenshake, sound effects, and bullet graphics made for very satisfying shooting. If I could make a suggestion - an "AoE" type weapon would be useful, with the amount of enemies that ends up swaming you. You don't really have enough damage to clear them, and you get overwhelmed. It's really nice when you get a shield next to two weapons, though, that feels great. Otherwise, it does feel like the shield's only purpose is some breathing room, since your tether is larger than its radius and you move pretty slowly anyway.
Great work! This was a fun bullet hell type game.
