What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
I can't/won't recommend this game. The original developers abandoned the game. The publisher has done nothing but lie, they are grifters. Instead of pulling the game from steam or at the very least, be honest about the state of the game and drop the price to $5.00, they leave it at full price and mention nothing, hoping the ill informed few will buy their abandoned game. I will never buy another game that has this publishers name on it. Be warned26 found this helpful
This is a dead game. The creators dropped it without completeing it. Very buggy with lots of, spend tonnes of time searching for any crafting item you really NEED, instead of actual gameplay. This game is still up for sale, along with a soundtrack and a bunch of other cr*p which still amazes me steam is allowing this game to sell AT ALL. Could have beena good game but evs got there money and dumped it and refuse to even talk about it anymore. Just the fact alone it has had no updates at all since MAY 2025 and s an early access game should have alerted STEAM but for some reason they keep allowing this to sell. Do yourself a favour and just set the money you would spend on this game on fire. It's worth it just to avoid the frustration of this game.14 found this helpful
DEADWARE bought it really early and this Dev certainly doesn´t like to communicate. Good concept, decent execution with some questionable design choices but it WOULD be worth it IF it were to see the full Release. Communication is beyond good and evil and an absolut Sh*tshow, March ´25. March of last year damnit. As it stands right now: DON´T BUY THIS GAME11 found this helpful
Studio closed with little to no telling of the player base, currently has no team under the publisher's umbrella working on it. Abandonware, avoid it as it's likely never going to be finished.8 found this helpful
This is abandonware, perpetually in early access3 found this helpful
I tested this game out in demo form and then in the beginning of Early Access when they released it. My first thoughts were, "Hey, this is pretty fun", then I died to a rat. Rollback through and kill said rat, only to be killed by my own exploration of the game world (I went out of bounds). It was ok. Fast forward to today (9-21-26) and this game is deader than the survival timer idea they used. I wouldn't have recommended the game before they stopped production and I certainly won't recommend it now that this is abandoned. Their last post was almost a year ago when they said they had "BIG CHANGES" coming to the game. ♥♥♥♥♥♥♥♥. Spend your money elsewhere. I want a refund for the time wasted in the demo and the free copy
