atari2600land updated his game GoSub2.

Release notes:

Added 2 more mazes (levels 13 and 15) Let me know if maze 15 is too hard, but keep in mind it’s supposed to be the last level, replacing level 14, which is the second-to-last level. I have room for about 10 more mazes, so GoSub 2 will have at least 25 mazes (GoSub 1 had 19.)
