A flawed implementation of lunar lander for the chip-8 platform. It contains a single level, and the ship seems to act pretty squirrely under some circumstances. Use WASD to add thrust to your ship, and the R key resets the game.
God, making games for old systems is hard. You really don't understand how much you've been spoiled by modern tooling then being limited to 16 variables, and one of them has to store the output of any logic comparison you do. I'm happy I did it though, because much like limiting yourself to hand tools to make furniture, it brings you closer to the craft.
