What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
A game I was greatly excited for only to have it eventually stop updating and die, the game now being "Fully released" as a free to play game (When the last update was 8 years ago when it was still in alpha). Simple yet enjoyable graphics with some interesting game ideas that will never see their full potential sadly. If your curious, play the game, but don't expect a whole lot6 found this helpful
Unfinished Game that was released from early access before it was finished, and then abandoned. Promising at first, but disappointing in the end1 found this helpful
it feels like an alpha... it has several parts missing, making it very frustrating to manage. you often need to micromaange. if you forget a manual control enabled the personel die, you don't even get a notification of a need or someone dying or dead.1 found this helpful
I've spent a disgusting longer amount of freetime on this than I wanted to this past week and my home, sleep and relationships have suffered because of it, so it must be good right?? Anyways, maybe one or two more days and I'll be over it, idk, I hope!!
really good but needs a tutorial
I have tried, tried and tried again to get up and going with this game. I just can't do it. I do my best to start out small, get water, get food, etc. Asteroids keep blowing me all to hell. I'm sorry, I just cannot recommend, in good conscience, this game to anyone.
