The game is fun but shooting the coin using the pistol is really awkward as the bullets have a smaller velocity than the coin.. Also I found that you are immortal when spamming the "F" key to parry projectiles as they restore you to full HP on parry and there is no window for ranged enemies to ever hit you if you constantly click "F". Howerver, this is good because it solves the issue of projectiles traveling through walls.
I also got caught in an infinite death loop by falling out of bounds on respawn when I cleared level 3. If you ignore the bugs and odd behaviour here and there (as expected of a game jam entry) its not that bad so well done!.
