It works nice on a VIA C7 with VGA (S3 UniChrome Pro) graphics running FreeDOS, via DVI out even.

Suggestions/feedback:

• Maybe add a README / information and pack it up into a ZIP file for download
• The simple game mechanics (sowing/harvesting with the tractor) is fun!
• A shortcut to sell all corn at once (instead of repeatedly pressing arrow(?) keys) might be useful, or a better key repeat / acceleration mode
• What about "retired" animals, can I sell the meat of these at the market, too?
• Keyboard input is sometimes laggy (keyboard input works fine in other DOS games)

All in all, this has potential! Of course, as always, the obligatory "this would look cool in VGA with Adlib sfx/music" (but this might only be added in the follow-up game, "Farming Simulator '90", as I understand.. ;).
