Sorry to hear that the Linux 32-bit version isn't working for you. What distro are you using? Although it isn't possible to see the whole level, you can press the space bar to toggle zoom out / in modes. The zoom out mode shows a much wider area.
No. It doesn't work. I don't think any Linux export of a game created with AppGameKit works for me.
However, Windows versions often work using Wine. Your game too. And, for example, all games from zxretrosoft as well. This man does not create Linux versions of his games. He may have had bad experiences with Linux exports of his games. *?
