What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
A good game to play every now and then and forget about life, very replayable, focused purely on gameplay and strategy.4 found this helpful
This is actually my first Steam review, but I felt like this game deserved one. Knowing it was made by just three developers makes it even cooler because you can tell they really put effort into it. I started playing thinking I’d give it a quick try and somehow ended up losing track of time. It’s just really fun to play and easy to get into, the kind of game where you say “one more run” and suddenly a couple of hours are gone. Big respect to the devs for what they’ve made here. Games from small teams like this deserve support, especially when you can see how much work and care went into it. Definitely worth checking out.3 found this helpful
Fun little tower defense game, enough room to explore different play styles but not too complex that it gets overwhelming. Good price for the product.2 found this helpful
It's incredible that this game was created by only three developers. If you're a fan of tower defense games, you owe it to yourself to give this one a try. The gameplay is incredibly smooth, addictive, and easy to get hooked on. It has a lot of diferent towers combos that are very well-designed, and the progression feels rewarding from start to finish. It's clear that a lot of passion and effort went into this project. Highly recommended!1 found this helpful
