Had the same scaling issue, but made it work thanks to a big screen. Liked the cylinder system for the revolver, that could actually lead to some fun deviations from the deck builder format if you expanded on it I think (For example, spinning the chamber, enemies putting in bad bullets, gun getting jammed, ext). I'd have liked a bit more feedback between turns, for example calling-out damage your taking visually / the enemy glowing red to indicate successful damage. I honestly didn't realize you could buy new cards until I looked at the other reviews haha - perhaps forcing the player to the shop between bounties might be a call. Either way, great job everyone :D
