A new, fan-made Astro Boy game has recently been released on the Internet. The only catch, it's in Polish! You can play it here.
Luckily, creator Łukasz Raszyk shares the controls in English on his devblog.
Left Mouse Button + mouse move = character rotationEven with these controls laid out, I'm still not sure how it works. I know it's supposed to be a game for kids, but any kid who can master this must be some kind of super genius or something, because I can't figure it out. Still cool to see Astro in a new game though.
[CTRL] + mouse move = camera rotation
[W] = move forward
[SPACE] = destroy a crystal cover
