Chromamancer

In this game, you play as a young magician about to complete his training. Approach of of the wizard's astral projections, and they'll talk to you (WASD keys to move). There's a number of things not implemented, but there's a lot of potential.

There's also a ton of lag in the first level, so watch out for that. Don't look at too many wizards at once to reduce lag.

You should be able to play the game without it crashing, especially on Firefox. Reload the page if it gives you an error before it starts and it will probably start.
