Glad you had a no-stress time playing, a break from some jam games for sure!
As part UX/UI designer for my dayjob I do agree that some stuff is lacking at best. All just came down to time, if this was like a week or 2 jam we'd have pushed & polished way further :) , just underestimated the 4 days & was a new experience working in a team for the first time :D
Did you manage to beat the final boss?- He's quite tough if you didn't pick up some extra cards :P
