The other day, I finally got around to releasing the Nspire version of Trapped (The 68k version is still in development, see below). Trapped is a sequel to Block Dude, featuring many new game pieces, including bombs, metal walls, and ladders. This game features 5 of the original 11 levels (I can easily add more later if I feel like it!).
Here is the ticalc.org description
Block Dude 2: Trapped is based on Justin Shaler's "Trapped!" for the TI-83/84 family of calculators ported to the TI-Nspire calculator. "Trapped!" is a sequel to the popular graphing calculator game "Block Dude" by Brandon Sterner. New features in this game added to the original Block Dude are bombs and ladders! This game features beautiful 16-level gray scale graphics and five of the original levels!
Trapped is also in the Omnimaga archives!
As for the TI-89 version, there is one bug with the graphics that I still have to fix. As soon as I do so, that will be released too!
