Cute character design.
Good sound effects and controls, though I feel like the base jump isn't high enough. I don't know if having to crouch to do a high jump is a good idea. Shooting still needs some work.
Bummer about no keyboard support, had some issues detecting my PS4 controller. There should be an option to use the sticks as the dpad.
Also there's some HUD flicker, I imagine you made it so when the player is not moving the HUD would appear and when you start moving it would disappear but the implementation makes it flicker some times.
Overall not bad for an early build, has some potential.
