It's good, it's pretty fun. Well suited for mobile gaming, OK for somewhat lower effort desktop tower defense gaming. Very pleasant aesthetics and atmosphere, less dense and deep than Rogue Tower but still offers a lot of interesting gameplay. Less chaotic and noisy than Rogue Tower of Bloons TD entries. Could use some work, and in the worst case it may be a game that's limited by it's own systems simplicity, but after my first few sessions I've found myself wandering back to it on occasion when I want a tower defense itch to be scratched, but don't want nearly the commitment or investment of alternatives.
