We are working on a level editor for Crazy Tanks. You can download beta version of our editor from here: http://www.bootant.com/TankEditor/ (only Mac for now) You can create rotate and move blocks around. You can create and move enemy tanks. To navigate use keyboard + mouse: shift + mouse button drag -- zoom in/out control + mouse button drag -- rotate option + mouse button drag -- move around You can't add levels directly to the game right now but you can send levels to us (firstname.lastname@example.org) and we'll add interesting levels to the game. You'll be able to download levels from the web directly into the game in the future.
