it's a good game - adding skills inventory that unlock with success and being able to place multiple towers without having to go back to the menu are the only suggestions that I can think of to make it better..... (besides having more levels...)
iisan - archers only go in towers - build a tower and you can put your archer there.
It's a pretty good game - I think the biggest flaw is that you don't get a bigger "bounty" for killing the harder creeps - you have to keep taking on tougher creeps for the same reward.
not a bad first start.... I like the paintball effect of the weapons. There's no ending screen and when a tower is fully upgraded the upgrade panel could use some work... keep 'em coming, you're on to something.
