Top critical reviews
The most up-voted negative English reviews in our sample, quoted as written.
“The game mechanic is solid and good. but having no speed option, no save feature, doing a guessing game when building a structure is diabolical in "defence" game.”
“the balance in this game is wildly off, I like it but the lack of saves for a 4 hr plus session makes this 10x worse than even Elden Ring, just bad design overall. great story ruined by design”
