I think your game was quite nice! It reminds me of one of my first game jams, I also picked a western theme for it.
I have to agree with the others that simply putting a countdown on a game is not really an interesting interpretation of the theme. The map also feels too large for what it is, I was able to complete all rounds I played on by simply staying close to the saloon, only on my first round did I explore the large area. (the ground tiles look like cauliflower lol).
But great job on the submission, you did great here!
