Hi guys,
I'm posting here in case Ariel gets a notification.
I've been trying to reach him about his Sokoban implementation on HP Prime.
Actually, I got myself a Prime G2 recently, and since Sokoban is one of my favorite games, I soon installed Ariel's version.
It didn't run on the latest firmware (some changes in the PPL language I guess), so I corrected some stuff, and while I was at it, I used the game to learn PPL programming and added some new features: arrow keys control, a high scores table, a last move undo feature...

In the end, it makes for some nice improvements, so I just wanted to show it to Ariel before making it available online
