Great concept ruined by a shocking number of inexplicably poor design decisions.

In no particular order:
-Building placement doesn't show you where you can place things, only whether your current spot is bad or not. Starcraft figured this out in 2010, there's no excuse in 2019+
-Resource buildings can't have any part of their collection circle overlap, which leads to the absurd minigame of trying to optimally place your resource buildings with no UI help. Again, Creeper World had this figured in the freaking Paleozoic, so no idea why it's hard here.
-A single zombie slipping through your defenses can snowball your entire base. Not an issue, except that there's NO QUICKSAVES, OR SAVE LOADING AT ALL.

For this and a number of other reasons, this game feels like some sort of unpolished Alpha project that somehow slipped through into general release. Which is a shame, because I'm usually a sucker for these kinds of games, and this would be exactly my thing if it didn't feel like such a slap-job.

5/10, would only recommend for the truly hardcore base-builder crowd.

game doesn't work anymore

Very good quality game. Can't stop
