That takes me back. I wrote one of these for the Atari 800, using a very blocky display mode. It had the Tron light cycles kind of play for 2 people, as well as a 1P snake mode, where the exit (a square "hole") would pop up randomly after the whole snake made it onscreen. That was over 25 years ago. *Shudder*
I downloaded and installed this, but haven't played it yet. From the readme, I take it that it doesn't have a window mode, and I don't want to do anything fullscreen right now. I'll try it later. Thanks for the link.
Edit: 5048 on Easy. Every time I lost it was because I got distracted, or thought I could fit somewhere I didn't. Not once did I crash because I had nowhere to go, or things got too hectic. Very slow moving at this difficulty. I hope it picks up on the others. It also seems to use the old paletized rendering, and that has problems on current rendering hardware (not just my NVidia card either--I've noticed this sort of thing over recent years on more than one PC). The colors will be way off on the menus, until I scroll up and down it enough to set it straight somehow. It worked fine afterward, until I quit. Then the colors went screwy again in the credits. It's all good for a freebie, though.
