The knockback from the gun was really smart, and I like the overall idea. The little limit on how many bullets you can rapidly shoot is a great touch too. My only critiques are that there isn't much visual feedback to really sell destroying tumbleweeds, and you can wander away from the cacti that are supposed to make it harder to dodge.
Hey thank you a lot! I planned on somehow generating the cacti and tumbleweed as you move along the map, but I wasted so much time on trying to fix the UI problem that I didn't have enough time to even think about that anymore... But still thanks for the feedback :D
