The concept for this is really good; I like the idea of switching between two skillsets ala Lost Vikings in a more action-based game. The risk/reward of stunning multiple enemies before switching is pretty cool.
My biggest gripe is the control scheme. Why is the switching button not reachable with either of the two hands I'm using to play? It feels like I need an extra arm. If I could e.g. right-click to switch, the interplay between the two characters would feel a lot more fluid.
Also, the moment speed seems a tad too fast for how zoomed-in the camera is. It's helpful for getting Maverick to the location when he's far away, so maybe just zooming out somewhat would be good.
It seems I sometimes took damage inadvertently (and initially, without realising) when I accidentally touched the stunned animal before hitting it (which happens pretty easily because of the movement speed). Maybe Maverick needs a bigger swing? But there should probably be some more obvious feedback that damage has happened regardless.
