PICO-8 Mouse Movement

Every day, something new! Today I played with getting the mouse working. Take a look at my code. I hope it's straightforward, but am happy to help out (leave a comment).

MX = Mouse X position
MY = Mouse Y position
MBM = Mouse buttons being pressed 1 = left, 2 = right, 4 = middle
TS = Tile selected. Hovering over a tile and left-clicking will show if  you're clicking a map sprite or not.

Enjoy :)
