Thanks for playing! I designed it to be a bit of a challenge, but I'm currently working on making the first levels easier. For the later levels, my advice would be to pause the game often to take your time and think things through.
Yea kinda my fault for thinking this was like those crappy cell games on the App Store Fun game this one is. Sorry for my short attention span tho ( •̀ ω •́ )y
Haha, glad you found your way to the game. I know it can be difficult. It always depends a bit on the perks you get. But I like to choose attack upgrades and use those early to expand. And if two AI fight I always try to hit the stronger one, while keeping some units in reserve.
