About this game
GAMEPLAY
Purchase towers to defend against increasingly difficult waves of enemies. Level them up and grow your defenses, finding synergies both between towers and status effects.
WIDE VARIETY OF TOWERS
Lots of towers means lots of synergies! Find the best build and overcome the waves of enemies with ease!
DIFFERENT ENEMY TYPES
Flying and ground enemies can provide a fun additional layer of difficulty. Perhaps you could use the weight tower to ground all flying enemies for a brief period of time, or the LMG, incredibly strong against flying enemies but not good at much else...
REPLAYABILITY
The base game isn't easy, and it'll certainly take you more than one try to beat it. Once beaten, you'll unlock up to 5 levels of difficulty, each with new random modifiers, harder enemies, and even secret towers! A low difficulty playstyle may be far less viable on a higher difficulty; thus, encouraging experimentation with new strategies to take advantage of the otherwise detrimental modifiers!
AWESOME SOUNDTRACK
Created by @creeper4207 on twitter, this pixel style soundtrack perfectly gels with the simple pixel art to create a chill and relaxing atmosphere.
