That game is fairly good. I think what sells it on this early stage is the spin shovel-copter air glide, the animation is smooth and its fun to do that, even though I have to press WASD in a circle. Air skip is interesting too. There could be possibility to polish controls to make them more robust. Fighting enemies is not as fun, they are quick and can hit you whether you are already in stun-lock animation or not, through shovel spin attack too, they can damage you through player's head hitbox.
Overall its a good little test of controls
