Thank you very much for playing!
Since the meat of the battle mechanics revolve around a 'use resource to strengthen it rather than getting umbrella XP', my main difficulty was trying to keep things balanced and I know for sure I can and will make improvements on those. I don't know if you tried it, but each character can equip any weapon or learn any spell, giving it a feel of Dark Souls where you can experiment with different builds.
I am glad you enjoyed it, I very much had fun making it and the jam gave me motivation to get it done to a playable point but for sure it does need some tidy-up and revision in future updates.
