pretty good
Loved tesla coils ever since playing Red Alert as a kid so this game hits the right spot when it comes to theme. The game looks nice, especially the attack animation of the tesla coil.
Overall I found the game to be pretty easy, but this is after realizing that if you click repeatedly, you seem to do more damage and lose almost no power at all. So keeping your mouse down and zapping shit down is a sure way exhaust your power and lose. This was a bit disappointing because I would have liked to charge up and mow shit down instead of clicking around.
Also what's up with the mini tesla? If money wasn't abundance, I would have surely cursed after buying that upgrade as it's shit. It shoots at totally random times, and doesn't seem to do much damage anyway. You would think you can let it handle a single average soldier coming ground way while you take care of the air threat, but nope, it can't even do that :P.
When I beat the game, all I got was a "congratulations, you beat the last level" which is, well, kinda disappointing. You need to give the player a bit better sense of accomplishment than that. Overall it's a nice game nevertheless.
