good little game, the beginning was a little tricky to manage, but after that it felt too easy actually. But nice simple graphics and it does what it is suppose to do. And plenty of upgrades etc.
Thank you for the kind words. And yeah, balance might be off a little, I've tried to balance it, but balancing isn't my specialty and AI's aren't that good at it either, just writing a script that plays the game and seeing how many times it wins or loses.
