The only thing I don't like is that I can't actually see what's happening on the field, since I pay all my attention to the left side of the screen, realizing that if I look at the creeps and how my turrets work, I lose precious time I could've spent gathering resources.
I'm not sure how to fix this problem, though, I guess it's an inevitable part of the game.
But, as I said, that was the ONLY thing I didn't like. I love tower defence games and this one is original and really fun to play, I can't help but give it a strong 5/5.
One of the best indie platform games I've played recently, it's beautiful. I love the fact that you can switch to the official site without losing any progress.
Don't worry, he's wearing an invisible helmet!
