Sint Nicolaas 1.5
This game really reminds me of the days of the good old Apogee shareware games, spending an hour to download less than one MB just to have a little fun.
This is even smaller than the old-school games I used to love. Weighing in at only half of a MB, Sint Nicolaas has sprite-based graphics that still look pretty nice. Although I would have liked to have a different option besides PC Speaker or Adlib, I guess I have to deal with beeps.
Outside of that, Sint Nicolaas offers a little bit of platform fun in a little package. It won't turn too many heads, but it might bring back some memories.
