French developer Mickael Soler has created this interesting retro game “web playground” built with WordPress, to show off his impressive parallax skills. Nice touch with the Space Invaders preloader. I can see some influences from the Gameboy 25th Birthday One Pager but of course with nice additions by Mickael.
