Pretty amazing game considering you can just fudge it and get a decent score but if you think about it you are suddenly a math genius. 4/5 for originality.
Thematically well executed, as far as reproducing the Warcraft look and feel (including some sounds effects etc.), however, it's pretty much just a VERY average tower defense game with a glossy overcoat of Warcraft theme.
You need to compete with other tower defense games out there that are leagues ahead of this. I know this is your first, but consider marking the upgrade level of the towers, and giving hotkeys for things like upgrade and sell. Adding some music might be a good idea too. Good luck in your developing.
There's a reason why top-down resource-based games are not done from a first person perspective but rather a "god" perspective. Learn from Populus and Simcity. Time to go back to 1988.
I would rate this demo a 5/5 for concept and fun if it didn't have a game ending bug on the level up screen as everyone is pointing out, where the game completely freezes and since there's no save feature you can't reload and try again. Wasting my time gets you a 2/5. Please fix, then maybe some of us could consider purchasing your game.
I originally gave this a 5/5 star rating prior to even having started to play it...I knew it would good. I could still be right, but I'm getting game ending glitches on multiple screens and I'm not about to go back and reattempt it till it has been addressed. If the Firefox browser is at issue, please state as such in the Description area. 2/5 until fixed.
