Well, I was playing full screen, and the cursor simply stayed as standard arrow icon. It was small and low contrast enough with the background that I found myself losing track of it quite a lot, so much that I had to pause to reacquire it, which invariably led to missing a few of the word bubbles. I frequently found that I'd moved the mouse off the screen, and so reactively jerked the cursor back and forth, which made it even harder to find the cursor again. I could probably have made it work if I'd kept trying, but it became more frustrating than fun, and that was enough to make me quit. I was far more interested in the actual ideas and logic than the bullet-game, so that was disappointing.
