Yeah there is a lot going on on the screen. Basically you want to shoot the enemies with your fireball (left click to fire in straight line) before too many spawn and overrun you so you can keep surviving. Also over time you want to collect the gold on the ground and then use it to break the gold walls to unlock new areas of the map. These new areas might have new spells on the ground that you can activate with the number keys that deal more damage or have effects that you can combo with each other to deal with enemies better. Every spell takes mana but you can refill mana with the mana orbs on the ground. The enemies look like little mushroom people they were supposed to be wizards lol and they telegraph when they move or shoot based on the colored tile highlights on the ground. Also there are spikes that activate after 1 turn so you don't want to stand still on those and arrow traps in the walls. Hope this helps and thanks for playing! :D
