I'm glad to see the legacy of the greatest MegaMan games ever made are still alive and well.
I really like the concept, and while the controls are a little finnicky for me, I think with some tuning they would be very natural. Specifically, the aim reticle moved very fast for me, while the mouse look mode moved extremely slow. This made it fairly difficult to control, but fixing it is just a matter of having control sliders for the sensitivity.
