I think if you could find a faster way to load the game engie this would be a much better game 5 mins to play kinds of truns me off... Good game might wanna find a were to bundle stuff and take down on all the hotkeys you have.
Needs to have longer waves then 5 much funner if it was like i say 10 waves or standard in games like this is usually 20 not a low 5 waves. Games fun and easy to play though

The initial download is 75MB. The rest of the game downloads in the background as you need it. 5 minutes download is very short for a game like this.
