There is a max hand size, it caps off at 7 cards. It doesn't make sense to hoard that many tho with how it currently plays. Everyone in my game gets dealt a bad hand, cuz i only have the 3 card variations 😓
As for the using cards during play bug, I completely missed that. The exact same bug happened on victory and defeat screens too, but I caught those ones at least.
Thanks for the feedback!
