A new take
A slightly short, but well working TD-game. Unlike most others, you have to keep your mouse at the ready, unless you're willing to loose valuable parts.
The parts do seem to come at very random intervals. In one game, i had enough resources to build a rocket launcher after the very first wave, while in others, i'd have 'em too late in the game to have the tower do much of a difference.
The towers act fairly intelligently. However, upgrading their range is a waste, since they aren't compensating for the creeps movement, and you end up with a tower that's missing targets more than before you "upgraded" it (splash towers worked alright with range though). Upgrading the towers damage potential wasn't that effective either, since it only added a few extra points of damage. Made me stick to upgrading their reload/attack speed, especially because it often doubled or nearly doubled the attack speed, in contrast to damage-upgrades, which didn't double the attack-damage. (I must note that i haven't tested all towers at this time of writing, though).
Having to wait for ones towers to be build before placing (just like command and conquor-games, lol) added a fine little twist to the gameplay.
Generally a really good game, and it gets a 8/10 - 4/5 from me.
