Dwarf Tower is a turn-based tactics game of tower building and spellcasting. Each turn you develop your tower by placing blocks, constructing rooms, and play various spells. Your tower can have Libraries (store spells), Crystals (generate mana), Dwarf Dwellings (give you dwarves to repair the tower) and some other rooms.
A small update has been filed.
Hopefully, the Doorbreaker spell should cause no more issues.
