This is so cool. I had so much fun changing my strategies, and figuring out when to run and buy, and when to fight. Some rolls tend to be very unlucky, but the game plays fast, so it didn't bother me much. Early stages can be breezed through by buying 12 dmg bullets, but third one and up gets really interesting.
Visuals are very pleasing and I love the design decision to include revolver reload sound when rolling instead of "boring" dice rolling one.
