Very cool and interesting game mechanics! I really enjoyed this one even if I didn't manage to get all the way through yet. That might be my fault though since in my first run I lost/transformed the warrior, and in my second run I tried not to transform anyone, which I guess left me underpowered later on. I do like the strategy involved of trying to choose between getting stronger dice sides vs more base HP and rerolls. I might have liked to see maybe a shop or something to add to this, since near the end I did have one or two characters who still had the base due to the options I was given.
I'll definitely try a run where I transform one or two units, but I also hope to get through it with a 'pure' party haha. I did get the dice stuck once or twice, but found the unstuck button in the menu.
Excellent stuff!
