Minesweeper in Ti Basic

Installation

Install TI Connect CE on Windows
Open TI Connect and plug TI 84 Plus into computer via USB. Under connected calculators, your TI 84 Should be listed.
Download the LIFE.8xp File
Open LIFE.8xp on the Program Editor within TI Connect (Three stacked boxes on the left)
Under the Actions menu, press "Send to Calculator"
Ensure installation on calculator by pressing "PRGM". MINES should be listed

Open MINES in the PRGM menu on your Ti 84
You'll be greeted with a difficulty prompt. This is how many mines (approximately) are spawned. I'd suggest starting around 10.
Once the minefield is spawned, use the arrow keys to move the cursor. Use the 2nd key to clear a cell. Use the Alpha button to flag a mine. All mines must be flagged in order to win, and if you accidentally flag something that isn't a mine, well you're out of luck.
If you die or win, you will be prompted for C. Press 1 and enter to play again, or 0 if you're done.
