Hella Fun :)
I'm gonna be honest and note that I didn't like it at first. You should continue playing after the tutorial and the first 2-3 missions. It took a few runs to hook me but now I'm really enjoying it. A DLC with more mission types would be nice though. Maybe also some more endgame progression combined with more mission types.
nice~~~~
болше советую чем нет. попервой игра очень интересная НО быстро становится однообразной гриндилкой ради гринда.
A suprisingly good tower defence game. IF you like TD with some variety, this is not a bad choice at all.
I got this game on sale and I'd getting it on sale. But it's really grindy. Meta progression is slow
It's a really nice peak tower defence. The soundtrack is catching too. Difficulty looks balanced. I played the story in easymode first, now in hard. It looks fair and challenging.
Solid little Tower Defence game at first. Very Cheap for the amount of content. Definitely a failed mobile game, ported to P.C. Gets very repetitive after a few hours in.
