The targeting needs some serious work, it's so frustrating to either walk into the enemy or simply have them target a stationary object with a ton of HP while getting destroyed. Lost all 3 of my guys in level 6 because they kept targeting boulders/furniture. Also it seems like the cost to rez/heal players grows far too quickly, from 0, 400, 1200 gold considering you need to start from the very beginning (0 gold, gear, levels) when you completely die.
The movement is a bit challenging at times to use, but I'll give that a pass. Wish it had a little more story behind it and potentially some save points. (every 5 levels or so) Getting really tired of having to start over because of targeting issues. Maybe use a right click targeting system or tab target?
