Space Tako 
I made Space Tako in 2013 as part of a small GameJam.
uses a lightweight Jump'n Run engine called "melonjs".
The game's goals are simple: Get to the other side of the level, shoot or avoid enemies you encounter. The graphics are intentionally designed to look cheap and some game elements are there to just tease you.
As the web and browser technologies tend to change pretty fast, I have to occasionaly come back and patch some things, that were broken with a new browser update.
