Your core mechanic is super interesting! It's also very impressive that you did this all in 3 days - the art is great and the music isn't bad for such a short loop. I've seen a couple games like this before (where you have to defeat past versions of yourself) but never quite like this. I only have a couple criticisms - the controls feel great overall, but I wish the jump height was just a little higher just because the cacti are huge (the platforming gets kind of precise at later levels and personally this game feels better to me as a puzzle-adjacent platformer than a precision platformer). And as others have said, playing as the sheriff feels trivial sometimes, especially for the earlier levels, since it involves basically no movement besides maybe jumping. I like the timer for the bandit though, it's a fun challenge having to balance making it easier for yourself in the future but still having to complete the level in time!
