If the physics were adjusted so that the impacts hit a bit harder and you zoomed in to slash from a slightly longer distance away, this would feel really good to play once the animations get boosted and juiced some.
I would like a separate control for sprinting rather than dodging though - crossing large gaps is a bit of a pain if your enemy continues fleeing at the moment. Also would like a slow lock-on system if you hold down RMB to increase the number of missiles fired in a single volley so long as you keep your mech more or less on target, rewarding precise dodges.
This is a nice foundation to add on to that you've built here. I'm eager to see where you take it.
