squares: speed

This is a from-scratch rebuilt version of my old little for fun project I made in college with vanilla js.

The old version is available here:

This version is simpler, it is just a race to see how many levels you can complete in 20 seconds and was created for the "20 second game jam".

The board on the timeout screen shows the most recent games that were played. the only data collected is a timestamp (private to the server), level reached, and the seed used during that run.

I'm contemplating updating this later with various different modes and things to do to make it more compelling after the game jam is over.
