Very interesting game! I do like the premise of having your graze being your main way of attacking enemies, and having to mix your limiting movement alongside range and graze box makes the game challenging!
Some feedback I have for the game itself is that having the graze bar completely reset when getting hit is way too punishing for this style of game, and lead to me snowballing into a game over multiple times due to not having enough graze to defend myself. Reducing the punishment so that it depeltes only half could help.
Good luck!
