The challenge was: how long will it take to write a JavaScript Tetris clone, stranded on a desolate island with only an old laptop and a painfully slow and unreliable mobile internet connection, and in addition barely possessing mere basic JavaScript knowledge? The answer: two evenings and one morning.
At first I used a list containing the locked blocks in order to be able to render them more quickly (in contrast to looping through the 10*16 'blocks' matrix), but maintaining the list when deleting rows showed to be a bit tricky. I then reckoned that was a completely unnecessary optimization and saved myself from the headache by shoving it down the garbage chute. The score system is from the original Tetris but the level system is completely improvised.
Feel free to try it out.
You are more than welcome to help out if you want to. Simply fork the project, make some cool improvements (possibly creating a new branch first) and issue a pull request. For example is multiplayer functionality currently being developed (see the 'multiplayer' branch) by the means of node.js and socket.io, so feel free to experiment with ideas!
