The first two chapters are nearly impossible on hard because the characters don't gain any HP between fights. It's SO much better once you get people to switch between.
Simple but original concept, I really liked it. Level 17's really glitchy, though, and like several others said, a lock-in-place function would be SO helpful.
This game is beautifully made. Great graphics, great tutorial worked into story, simplistic yet challenging gameplay... 5/5
(Also, I feel really bad for killing the foxes after I have the fox ears XD)
