Had to finsih my thought(1000 char limit) - To be fair though this is a great start. A good begining production to learn from. However you have to recognize that if you put even the most amazing game of solid gold and rainbows(which this isn't) out on the internet, people WILL trash on it. So don't get bent out of shape just take users advice and make it better. Then when you make your next game it will be more refined when you release it.
It worries me that this is v1.5. This is an improvement after v1.0? this should have never been uploaded in the state it is in. "Uavailable"=Way too obvious typo. Poison is listed as an attribute, but no towers have it. All of the towers are listed as ground towers, yet there is nothing else, so you shouldn't list them as ground, because then we expect you to have a flying creep/anti air component. It has been said before but upgrading most towers hurt the tower. (I know you were going for showing an incrimental increase but that isn't what it shows) One tower design(cause changing colors doesn't count), One tower shot design(again changing colors doesn't count if you only use one shape) the entire thing could have been drawn in 30 min in powerpoint using quick shapes and texturing.
Two comments, One question.
1. Awesome game
2. There should be a contest to see who can make the least efficient lvl 1 design.
Q1. Why doesn't this work? (Pls + if you like it :D )
