Great way to pass time. What ever happened to online gameplay? Love this game, looking forward to space stg 4 if it ever comes. This game is very fun and surprisingly well-developed. The game is a good mix of challenging yet simple. Although, sometimes it's difficult to obtain resources for ship upgrades. other than that I have no complaints, fun game

The game is over by the time you get to figure out how to get to the next one will be there at the end of the next level to the time you have to figure out what the next steps of the lever

This game is awesome, so long I have come across planets very realistic if this was real. Hoping the developers are just getting started

I keep coming back to this game, and It's still very hard to our down. The strategic map is well done, missions feel challenging without being too hard at first. The tactical battle layer is where this really shines. Turn based, and tech advances feel like they make a difference. The ship types feel different, learning what a class does well and capitalizing on that makes a large difference. I'd recommend this to anyone. You have option of watching videos but fantastic free to play.

Horrible garbage. Tutorial is 60 seconds. Battles are ridiculous. 1/5 of screen is blocked by ad that doesn't go away. I bet there are way better space strategy games out there.
★☆☆☆☆Jim· May 24, 2026
Great game, bonus levels are ridiculous, game engine launches missiles without sounds like every other level as if it's cheating....and game engine can come up with bonus weapons it shouldn't have thus making bonus levels unbeatable
