Overview

What the game lacks in artistic talent, it makes up for it with fun gameplay!
Instead of following conventional norms with towers, the game gives the players the reigns to do it all themselves.
You start the game off as a novice, knowing only a handful spells, and earn Wisdom points by completing levels. Those points can then be spent on unlocking new spells, or to focus your knowledge on a topic, unlocking a bonus for you to take advantage of in your other levels.
The progression system is very forgiving and non-committal, allowing the player to change unlocks at any time before a level starts, allowing the player to try a variety of strategies.
The game offers the player various challenges, including but not limited to: resistances, target manipulation, and devilish map design.
There are also optional bonus stages that allow the player to become more powerful if they wish.

Gameplay

Each map offers a slightly different experience and challenge to overcome.
Some maps utilize multiple paths to divert your fire.
Some maps use the terrain to limit tower placement.
There's also clever wave setups to deal with, which use differing enemies to complement the other's weak points.
To defend yourself from the onslaught of monsters, build a tower (or two), make a gem, then place a variety of spells in that gem. The gem goes into the tower, then deals with the rest.
Towers have a variety of targeting modes at your disposal.
Focus your powerhouse towers onto the highest HP enemies
Or put slowdown spells on the fastest enemies.
Or put slower projectiles on closest targeting, to ensure they don't miss.
Sticking to first targeting is not always reliable, so watch out!

About the spells

spells operate on an individual basis, and do exactly what they say - This creates interesting scenarios thanks in part to the playhead concept, which controls which spell is being cast at the moment, which is moved whenever a spell is cast, and sometimes by the spells themselves.
Order matters - the order in which spells are placed can greatly impact the way a group functions overall. One misplacement can result in a significantly weaker gem, or one that behaves unexpectedly
Modifier pools - modifier spells affect the way projectiles behave, from doing more damage, to homing on enemies. modifiers can be stacked as many times as can fit, each cast adding to a "pool", which is then cleared upon casting any projectile, save for certain select spells.
