I love the fact that we can cut 5 mins from the build/upgrade time. i like the combat and the alt fores feel natural(me being a LoL player am used to qwer skill set) and its nice how the lvl screen shows you enemy resistances(beam and energy etc.). Great job so far. Robucks i guess are for other stuff but i like how we get some per A.I lvl. I think it'd be nicer if we could upgrade several buildings at once (maybe 3 max).
