The program only wants to run once . . .

[Kernelpanic]

What about that screenshot shows it running incorrectly? That's what I'm missing, it looks like it ran just fine and hit the case where `_KeyHit` returned zero

Is the problem the "Untitled" in the title?

Again:
I start the program, press the space bar, and it is displayed correctly. I start the program again, press the space bar again, and it displays "unknown". The same thing happens with "ESC".
After deleting the exe file, it works again, but only once. Then the game repeats itself. I just tried it again.
