I made an edutainment game for resistor color codes. For each level, you have an enemy ship firing at you (the speed of the torpedo increases as the levels go on), and you have to match the color code to the number. If you pick the wrong number, there’s a delay before you can fire again. Pick the right number, and you get some points and warp off to fight another enemy. (I’m taking an electronics class and I need to learn this, so this will hopefully help me drill color codes)
I also worked on an RPG, and by “worked” I mean I did some sprite edits and made a basic level editor.
