Nice game, I wish there was a bit of more controls on characters, but it's a game jam game so I can't complain.
It would be nice to have between battles the time to check your characters, maybe clicking or hovering above them to see their stats. Level, Attack, Damage, HP and so on, so you can take better choices when those pops out.
I have no much understanding about mana. How does it works? In the rage of the fight I can't keep an eye to see how it's handled. Is it a collective thing or individual? I felt that having 1or 2 Clerics doesn't change much between them and the chances to use their ability.
I got stuck at Day 41, I had a grid of 4x4 heroes and a summoned mushroom. I think that mushroom was from the last battle and once I summoned a new one at the end of the battle, when the new battle started the game hanged. Probably it's a matter of limiting summoning when there is no grid space or increase the grid where to slot heroes + summoned creatures.
Overall a nice game for the auto-battler fans :-)
You need to bring your wife to the hairdresser more often to get new nice ideas :-D
