Awesome game, managed to drag me in for the best of a week! Couple suggestions/comments:
- We could use some on-screen indication of a tower with low health.
- We could have some small indicator for the abilities recharge timers... its very tiresome to be constantly checking.
- We can swap abilities that are on cooldown, meaning I can cast a Drone, swap it to something else, then I have the drone and the new ability available. This defeats the purpose of the ability bar since I can cast them all at my pleasure. Either make it so the entire ability bar is displayed with a click, or make it so I cannot swap abilities that are on cooldown.
- There should be a faster way to earn gold for the more expensive upgrades. I didn't even bother getting the extra drones for my Thor since they where so expensive...
