Great game! I've been looking for a sim tower type of a game for a long time! Would be nice, if you could add the elevator to not have to click on each floor but kind of drag and place just like demolishing them.
To beat all the levels, this combination is foolproof: TURTLE, RAIDER, GOLEM, HEALER, RAIDER, RAIDER, RAIDER, RAIDER, GOLEM, HEALER, RAIDER, RAIDER. Keep it alive for others by pressing plus on the right side.
