“The game was Perfect until they ruined the UI Hud & they refuse to add an option to get the old one back. Gameplay was awesome & now it's headache inducing with all the buttons changed & the ant icons being overly…”
“Overall, it's a very enjoyable game. Enjoying both the RTS and base-building elements. On the downside, it's almost unplayable on my MacBook Air M4. First, the cursor is NOT aligned with the UI and I needed to…”
“This is one of my favorite games. When i was a little kid i would wait until school is over and right after i come home i would play this game until nightfall or in other terms the game is just that good and you should…”

“Well.. if you ever wanted to learn about Ants and how they function with a fun twist, RTS colony sim? Then this is a game for you! Had a chill time with it, and can't say that its overly easy as well, cuz I had to…”
“one of the only epic ants game, and an epic narrator”
“A fresh, easy to learn smooth game. Impressive visually with fantastic music and strong voice acting. I've never wanted ants to win until now. The base building and rts elements are very straight forward--no experience…”

“This game has been in my backlog for a long time and I have been sitting on gold. It has a solid take on RTS mechanics that lends itself to the ant lover in me and my reflexes not being up to par for standard genre…”
“This is a fun game that is a big departure from my usual games. My favorite kind are medieval city builders so going in I wasn't to sure. But the tutorial was surprisingly simple and easy to get a hang of. Story mode…”

“There's just something different, highly addictive, relaxing, and intense (all at once) in this title... It's definitely one of the most unique and well made RTS games I've ever played! Honestly, an awesome game well…”

“AMAZING game. Replay has bean GREAT!!! I just wish there was more. Possibly a next chapter where the colony gets loose and has to learn to thrive and progress. But all in all, GREAT game. I LOVE IT!”
“Short campaign but the last few levels were fairly fun and challenging, I'll check out the hard mode at another time but overall worth it.”
“Fun and original game. I'm just a bit frustrated for now because of the lack of variation in the strategies you can use (I haven't discovered the whole game yet so maybe it gets better). I would like, for example, to be…”

“It's an amazing game thats also educational. I wanted to leave this review after reading their latest news update about their DLC and about the new content they're releasing. Not only are they listening to their players…”
“This is the freshest, most interesting RTS I have played in years. If this had multiplayer I could see a lot of people having a lot of fun with this. So many different types of ants that play differently, the focus on…”
“Super fun strategy game, would be to cool to play with other players though too.”

“3.5/10 gameplay loop is dull thought this would be like pikmin, one of my all time favorite games. nothing at all like that. - not much you can do with your ants. just build hoard and send hoard. - cant build any…”

“Very entertaining game. Very fun with the addition of remix mode. If you have any amount of interest in ants it is a crime not to buy this game. Could use a bit of work on the viewing though. Let us turn the camera!…”
