This is a tunnel game by DJ Omnimaga for the HP Prime calculator. It was ported from the 39gII version released earlier in 2013. To play, run the program and avoid walls with UP and DOWN. Exit with ON. 

Note: This game was coded using the HP Prime emulator and tested on a real calc by Critor, before the calc's release. As a result, I do not know what method this calc will use for file transfer yet. However, I know that if you ever want the source code, just open the hpprgm file in Wordpad, then you'll see the source in weird format. It is still somewhat readable, though, so you can use it to copy the game by hand or for code use (give me credits if you do, though!)
