Got almost all the buildings upgraded and then I got a soft lock when trying to pick a ball. I also managed to see the final? boss, but didn't get to beat it. Fun little game and loved the little village up to with villagers running back and forth. I do believe the arcane ball seems a bit bugged because a couple of times it would make the enemies invulnerable to getting hit after getting hit by an arcane ball. The volley also was not very helpful and I tended to avoid that one as much as possible. But all in all a fun little game.
