Loved the DEMO, kept smiling all through while I was playing, it really brought back the nostalgia.
My Chef's Kiss to this game is the fluent animations into the game play chopping the top and bottom sprites into one character for a seamless aiming and moving.
Also I loved the art style, I just have to give the animators credit because this kind of art style is usually difficult to animate and they killed it with the emotions they gave the characters.
Overall Awesome game, can't wait for updates.
