I would love a glitch minigame where you play a chicken. You have to attempt to get to a finish line (a neighboring street) before glitches in the level you're in harvest X amount of grain from you. In level 1 it's really easy because they have to harvest a ton for you to 'lose' - but each street the level they need to harvest gets less and less. Perhaps there's also powerups (like coins for chickens) to add a higher grain-maximum and replenish your grain.
Perhaps it's a mobile minigame.
Perhaps the first time you play the game in a given Glitch-day, the amount of grain you have at the end of the game (the amount you 'win' the game with) gets transferred to your glitch as a reward! You can, of course, keep playing the game that game-day, but only the first time nets you a reward.
I'm guessing that the glitches trying to steal grain from you would be the 'computer' and it wouldn't be running down actual in-game streets, but a standalone mobile based minigame.
