Outpatient memory erasing.  Like high speed "Operation", but instead of tweezers and a cartoon patient, you're zoomed in on MS Paint wielding the eraser tool.  Now Hiring.

INSTRUCTIONS

click and drag to erase pixels matching the color displayed at the top of the screen

erase a "fragment" pixel with no neighbors to get bonus combo time and earn money based on your current combo

the memory will collapse on its own during the procedure.  Avoid the dying gray pixels

press M to toggle sound

Note: sorry, ran out of time for sound balancing (and a lot of other stuff...)  Hopefully it's okay for most people
