I’m currently developing a web-based video game using HTML/CSS/Javascript and PHP. You can get the code directly from the GitHub Repository. I live-stream game development every Tuesday at 9:30pm Eastern on my twitch.tv channel.
About the Game
The game is a physics based puzzle/RPG. While different, you can think of it like angry-birds with powerups. You click/tap to create black-holes that affect your character. You have to collect power ups that you can use to upgrade your ship while attempting to complete each level.
