Thanks everyone.
This was the first time I tried a 16 color constrained palette Stuart, so I'm doubly glad you enjoyed the graphics.
I didn't get around to sound effects before the deadline, so I'll not add them now, but I will circle back after judging and pop something in. It's running in Super Jamicom, a free 16 bit game jam online IDE I'm still in the middle of writing, which is still missing audio tech; this'll be a good excuse to dogfood the new tools.
