Interesting concept, I was wondering if anyone would try a puzzle type game for this game jam with a 10x10 grid. The grid was causing me to see that optical illusion where you see dots appear in between the lines.
The lighting on the bottom right square causes the orange squares to appear pretty close to yellow, might want to center the light.
Since there's a cap on how high of a score you can get, I don't think the high score is super necessary. Not sure what mechanic you could introduce to make things more interesting -- maybe the board could randomize every time except for the four corners?
