I've made a browser game where you need to land a SpaceX Super Heavy booster into the Mechazilla's chopsticks.
The game is built on top of HTML DOM and is powered by about 300 lines of JavaScript.
The source code is not obfuscated or minified - you can check it out. Nothing fancy, but it turned out to be a lot of fun to play.
Give it a try and share your impressions
