Made it this far and then it froze :/ loving the game though, I've put way too many hours into this!
Cool, nice to see what is actually going in in the "real" end game, I've never made it that far. Dang, too bad that freezing issue is still somehow reachable. Do you remember what happened prior to freeze at all? Looks like you probably were holding some card that somehow got recycled and hence got stuck trying to place card that doesn't exist. Thought I fixed it already but I guess there is still some way to replicate it.
Also, guess I'll need to do some grouping for the skills icons. It'll look much less obtrusive if all those dupes were stacked under one with a count label or something. Any idea what made those empty spaces appear? Are those some of the two colored skills maybe bugged somehow? Not seeing any of those on the list...
Does it still get too easy even with the enemies and the less open levels?
Correct, the crash occured when I went to place a tile and then tried to put it back (to grab another tile).
It does get a bit easy towards the end, you can end up with so much life that it doesn't really matter if you have to block of large sections of the map.
Maybe a max limit on health might help? It would take a bit to work out the sweet spot for late game difficulty, perhaps around 50
