Fun game with addictive gameplay loop! One possible improvement would be that the roll mechanic is a bit confusing, since the character rolls toward the mouse cursor instead of the direction the player is moving.

Polished and fun! I like the idea of a cowboy fighting cacti lol. 

Really enjoyed this type of shooting game! I enjoyed the idea of having to dodge enemies and gain buffs and cooldowns- similar to a rougelike. Only thing I can think of is fixing the roll mechanic. The PC is rolling in the opposite direction from the direction being pressed by WASD. (If Im running left and I need to roll left, I roll right instead.)

Otherwise, great game!
