As suggested by Bisam on tiplanet, I have finished a version of the game "Isola" in lua for nspire.
If you're not familiar with the game, it takes place on a board (usually 7x7, mine is 9x9), where players take turns. On your turn, you must first move your player, and then add a hole, in attempt to trap your opponent.
This version features multiple themes, as well as awesome mouse controls!
