Some suggestions:
- Add a bar where you can see who can do some actions (I hate click every guy to see who has done his action).
- 1 shouldn't be the normal damage. I hate that I can only kill with criticals.
- Reduce the costs of new trops. Or even give the army automatically to the player. Buy your warrior 8k gold, improve him 3k, see how he dies with the first hit is priceless. When the game starts, with 0 armor and weapon it's fine, so work basing on that. Personally, I'll remove armor and weapons and modify the damage and defense basing on what you improve with leveling.
-Some skills should be passive. Show the description of each skill during battle while you select it with the mouse. I think some lasts more than one turn, so say it on description. Duration should be shown more clearly. Add a cooldown to use again the skills, maybe not to all, but yes to some.
How to win: Turn all the lights green and use the Entropy sphere. In some levels you may win too many Paradox, so use your own skill with one or two semaphores. Voilá.
Oh, and remember that this is coincidental magic.
Easy Sparta badge: Buy a Fan Tower and a Missile Turret, max both of them (damage is not necessary) and get a Space Laser with 2 ammo increases. Victory.
