Cool another dev log! If you want to make your game look like it was made in ms paint, I've found that unpolished lines (like the janky eyes in your sprite) and authentic colors really sell it. I'm using winxp's paint colors and my game looks appropriately hideous.
The idea for your game sound neat. I get sick of seeing platformers in every game jam, but Iove it when one comes along with a cool gimmick. Looking forward to your game!
