I think it's a nice and somewhat underrated tower defense game, especially for being free, I've been playing it and I've enjoyed it quite a bit. It's one of the few tower defenses that I like, that keygen soundtrack is very enjoyable and the gameplay is simple but very entertaining, the resource system is interesting, the graphics although very minimal are good to look at, I like the art style. And, I like the grind. The upgrade system of every tower plus the way some maps are put out leave you with alot of possibilities and the game really does open up after a while, it seems very simple at first but there's some good depth in it and that surprised me. The things that I don't like is that there could be a few more towers and the fact that you can pay 5 dollars to get double resources but afaik that's the only in game purchase, and without that the game is still pretty fun, also the sound effects could be better, the soundtrack like I said is really cool but the actual sound effects are kinda bland but that would be it. I really like it and I was wondering what any of you all might think about it.
