Fun! Fortunately I read part of Kobato's comment before playing so I had some sense of how the mechanics worked; without that I think I would have had some confusion about how the hero stock worked. It ultimately feels like a bit of a peggle-esque physics puzzle game? Some levels (particularly 10) felt a little finicky, but overall I enjoyed my time with the game; good job!
edit: Oh, one additional note: The game doesn't run on Chrome incognito mode, it fails with a "[UnityCache] indexedDB database could not be opened" message. I think on older versions of Unity you need to turn off "Data Caching" in the player options for that to work? Newer versions seem to have fixed it.
