Its a solid enough prototype, but it really needs that time in the oven. Also, there doesn't seem to be any incentive to bounce the bullets intentionally, and the gun is accurate enough and the enemy hitboxes big enough (and the player moves fast enough even without the dash) that it's unlikely to happen on accident, so it doesn't really come into play?
I do like the gun shooting animation/particles though! And the dash is nice and responsive.
One more small note - the player's heath bar flips along with the sprite :]
