This game is completely and utterly broken!
And I love it!
At the beginning of the round, move to the left and stand in the spawner. Now begin randomly casting spells, no matter what, no matter if the timer doesn't allow it.
The timers will spin out, the game begins to lag and all the waves get spawned at once! The game runs at around 0.002 frames per second and nothing works.
With the game as broken as is, just keep casting random spells and funny shit will happen! For instance all the spells coming out of you at once. Or some of the enemies beginning to fly! It will always be a surprise in spelling chaos.
I actually don't know how that glitch got triggered, but I was only able to replicate it by moving to the left...
