Moving platforms are too slow! Felt like I spent more time waiting for those than anything else, and I had no reason to kill monsters in the last couple of levels due to maxed upgrades. Otherwise entertaining game, good potential!
I must apologize for my rash comment about the Intro music earlier - first of all, Hans Zimmer didn't compose the music for Wall-E, Thomas Newman did. Secondly, I listened through most of the songs and didn't find an identical song, however it is VERY similar to the piece called "Axiom". Perhaps it was the likeness that confused me. I did check out the page of your music provider as shown in the credits, Incompetech.com, and the first thing that pops up is YouTube licence issues where he claims that other artists are stealing his work - make of that what you want.
Hands down, the best free FPS I've ever played, and probably the best game I've played on Kongregate as well. Very challenging, those 5 stars really feel like accomplishments - very polished and gives a great overall impression. I even like the 'advertisements' inbetween, thumbs up for minecraft reference! Solid, fun, entertaining, I just wasted 2 hours without noticing :]
Finished it in Easy mode, didn't have any problems but then again it didn't feel too easy. Cool concept, I like the cone-idea of TD. Good game, 5/5 due to potential color-coding of cones and adding more upgrades.
