Today i discovered PostBot, a free, homebrew game for the GameBoy and emulators.  It made for a fun rainy-day activity.  The premise of the
game is that you are programming a robot to maneuver around obstacles
and deliver mail to mailboxes.  The game has eight levels, each level progressively more difficult than the prior level.  The robot has six operations: turn left, turn right, move forward, deliver mail, do F1,
and do F2.  The main program has space for 10 operations.  F2&F2 each
have space for 5 operations, and recursion is allowed.  Clear a level
by delivering mail to every mailbox on that level.
The game can be played in a browser-based GameBoy emulator, and there
is also an option to download the ROM, which is roughly 64KB in size.
I played it in the zboy emulator on FreeDOS.  For download links, see
below.
