If you like Tower Defense Games where the player actively participates by walking around and slaying enemies, then this game is for you! I find it very fun, and I love the upgrade and RPG aspect as well, where you can get better items and skills. Very fun game.

My only two gripes are as following:
1. 1080p isn't in the game by default. You have to manually add it in the games Steam Folder. (Look up how to do that online)
2. The game is quite expensive at €20, and while fun, I don't think it's worth 20 euroes. Get it on sale! I personally got it in a bundle, so I feel like I got value for my money.

Games fun! :D

TL;DR
6/10 overall , buy The Incredible Adventures of Van Helsing instead
Graphics - 5/10. Adequate, nothing particularly bad nor good
Gameplay - 4/10.
UX/UI (MKb) - 7/10
UX/UI (CNTLR) - 2/10. Reason why I refunded. Horrid experience, only reason it's not a 1 is it functions. Mostly...
===========
Very generic Tower Defense coupled with a fairly jank action rpg experience. Compared to TIAoVH, much worse game. UI is absolutely horrid for controller. You can't hotswap to a controller from mouse & keyboard either, gotta fully restart the game.
