Cool concept, liked the idea of prepping for a duel throughout the day, and then fighting for a bounty at high noon.
Could use some balancing so that there's more incentive to do things during the day, I found myself spending all my money on upgrades and/or the bank in one day, and then just entering/exiting a building to get to the duels/invest at the bank.
Loved the artstyle and player animation.
Overall this was a great submission, nice work!
