Hey guys, i'm sharing some assets i've created for Tower Defense Games.
There are some backgrounds for grass, sand, dirt and snow levels. Also a dozen examples of levels ready to be used.
As for a plus, i've put a Construct 2 project sample with the pack.
Check it often, there are updates constantly.
Also, check the rest of the assets available at the website while you're at it. There are some cool stuff and freebies.
