This Game is about customizing your turrets, so you can defend your Magic Core. But be aware, your Power is limited. You gain Magic Power with every Wave, which is your health, but also your Currency to build and Upgrade your turrets.

The Game was made for the Unremarkable Game Jam 2

Tutorial

Build Towers with your Magic Power and Upgrade them, to be able to place more Runes in them. Each rune enhances the power of the Tower. And if you are able to place in a 2 by 2 or even 3 by 3 grid, these enhancements are even better.
