Simon: 6 Open Source Clones Compared
asdf is a minimal, keyboard-only browser remake built for the 2012 js13kGames competition (games under 13KB), recommended for WebKit-based browsers like Chrome or Safari. Ellaz Follow Me is instead one game inside a larger, actively developed platform of 23 free browser games with no backend — its art is original SVG and its sound is synthesized in-house, with progress saved locally rather than to a server. Follow ME is a separate, now-halted Phaser-based clone with no stated relation to either of the other two.
