This was really fun, like the Western setting!

This was a fun wee game! Nicely done. I noticed it was a one-person job.  Nice work in the time you had to make it. It reminds me a lot of the offline Chrome game. 

Extremely simple but cool! I don't know why but the fact that bullets collide make it more...interesting? Idk, but nice work!

Simple but really fun to play and really nice art style. Some added background music would be nice but overall great job :) 

An addictive side scroller game, I liked the cancelling out of the bullets also.  Good fun and nice graphics.

Super simple and competent. Reminds me  of the Google T-Rex game. I don't think it fits the theme very well, and there should be a reload button. That said, I like the old-school Atari 2600 Pitfall graphics and there are a few nice touches to the animation, like the enemy kill and the cowboy reloading the gun and taking his hat off. Nice work!  

Simple but consistent! I particularly enjoyed the fact that when two bullets collide, they cancel each other out. I found it intriguing for some reason.  

Adding some background music would definitely make it for a more immersive experience.

All in all, well done!
