I really like what you did with this tiny concept, attempting to make a one off gag into a thing of its own.
What really impresses me are that two of the medals (won't say which or how) play off of how small the game is. It's very clever to work with limitations like that. A complete game may be fun, but I like how you were true to the brevity of the original joke.
I had some fun trying to figure out the medals. I got far enough past the shopkeeper once that I saw the edge of the level and thought that struggling to get there was offside. I also liked trying to play jump rope with the shotgun, but I couldn't dodge more than one shot.
