Cool project, place turrets, go trought the wave, upgrade, rince and repeat. The style is great and the core system works fine.
I think the biggest bang for buck addition would've been a little tutorial or make it clearer how the wave system works, i was almost going to quit but figured id try a little longer because i tough the waves were just restarting without progress. The load LAST level was confusing me at first, you are basicly restarting the last selected level, but you do keep the upgrades you made at the end of the wave. Very slow start, for the first few wave you dont really get enought to get an upgrade and its not really clear if its normal or if you are missing something. But like i said, the core game loop is there and is playable, good job, 7 days is not a lot of time! Once the ball gets rolling, its fun to see the AVT explode
I really like the simple layout and the turret placement, would make a very cool arcade style game with multiple levels and themes.
