Midnight Snack is an beginner-friendly game revolving around getting out of bed, making and eating a sandwich, and going back to sleep. You are graded on how fast you can complete the game. Once you're aware of the few caveats you need to take care of before getting to bed (turning off the lights and sinks, putting away your butter knife and food), it doesn't take too long to beat the game with the best rank. I think this game could be good for introducing someone to basic parser gameplay.
