[SPOILER] Some pixel perfect clicking required to use the pliers on the rivets was deflating, it should have worked when using the pliers on the plate itself. Had to use the walkthrough due to that and then lost interest.
Locked items should go either to the bottom of inventory or a separate area. Otherwise you have to scroll though all of your locked items to access anything in inventory.
It's off to a very good Runescapey start. When Tsu city opened up, I thought "Great, it's all just getting warmed up." But then there was nothing to do there and the game was over :/
If this could be worked into a larger more complex game, say like an RPG which uses this as the battle format, with custom armies and things like that, this could be very good.
I figured some people might not be looking at their screen when they lose, and had planned to manual reset (but keep auto-restart on), so I wanted to give them enough time to check back on the game and click it. I suppose I can reduce the timer. One minute won't hurt at all in the long run, though.
Some of these % calculations are wrong or misleading: "Bone Colossus draws near. Bone Colossus takes 32 damage (81% remaining). Bone Colossus takes 32 damage (71% remaining). Bone Colossus takes 32 damage (61% remaining)." My first 3 hits were the same amount, yet one took off 19%, the next 10%, and the next 10%.
