Island Drop (Tandy TRS-80 MC10) by Jim Gerrie
A downloadable game
Here is a 10-Liner for your 2026 contest. I've included the source code (.txt) and emulator cassette file (.10) and some screen shots (.png).
I've also included a version of the source code with extra comments inserted.
The latest VMC10 Emulator can be downloaded here:

The program uses SPACE to drop and the O and P keys to steer your parachutist. Use ENTER to restart.
For additional instructions, just LIST the program after loading.
You will see some REM statements listed after lines line 0-9 (the program)
