Great way to pass time. What ever happened to online gameplay? Love this game, looking forward to space stg 4 if it ever comes. Anyway, 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 recourse for ship upgrades... other then that i have no complaints, fun game

I'll upgrade to straight 5 stars if there is a confirmatory button before surrender, preferably a 5 second delay before confirm button can be toggled. If desirable this setting can be toggled on and off. Sometimes my phone has a mind of its own and press the surrender button on its own, causing me to lose decisively winning games and hours of progress. That's why I can only give a mediocre rating at best. Excellent game otherwise.

I had actually given this game a 5 star rating in the past (2016). Although there has been so much improvements, I reduced to 4 stars for one reason. When requesting for reinforcements, can you give us the option of selecting a multiple number of reinforcements at a time. Other than that, I love the game so much, I've had it on everyone of my android phones that I've owned over the years.
