There needs to be some better AI for the units. for example, if you click on a mine, they'll just wander in circles and take fire and die without returning fire or even finding a place to stop. Also, the focus needs to not drop after every order. If a set of units is selected I should be able to click on a different destination without having to hit space again to select them all.
The game itself, however, is pretty cool. I like the option for a constant stream of units.
Needs some tweaking in things like the reload time and available action field. I do like the central point of defense, though, and having to lead some asteroids, but shoot straight at others. Perhaps a difficulty setting to increase or decrease the asteroid spawn rate would help. I do agree that sometime it feels like a sitting duck, so maybe the energy bar could regenerate over time, but pick up the pace of the incoming to compensate?
This needs some work in the area of cost vs upgrades, but overall the mechanics are sound. Perhaps some additional tower information, like fire rate, might add to the feel of depth.
The "strategy" portion needs some gameplay improvement. Having a strategy game where each move is then a micro-managed battle is far too long in playthrough for a game where the player can't save.
I just came back from lunch. I'm on level 419, with 64 million gold, and they still barely get out of the gate before dying. I can't spend the money fast enough to not make a profit off that 5% interest. Definite scale issues.
