Huh, there must be a rounding issue with Sen's floating animation, that's funny. You're definitely right about the energy consumption numbers for the teleporters and the radio tower, I meant the put those in but I guess I just forgot. A wave timer might not be a bad idea either, I'll have to think of ways it could be incorporated into the UI. I want to keep the rest of the screen relatively clean, so I'm a bit opposed to adding more health bars and damage numbers, but putting that info in the build menu might help to compare relative values at least, I'd be willing to consider that.
