I use tileworld on Mac mostly, and Lynx exclusively. Whenever I go back to MS mode, it looks so clunky. I also run it under Linux in Virtualbox. When I am really desparate to crack a level, I can do an OS snapshot / revert to snapshot as a save/restore game mechanism for Tileworld. ( you have to pause the game before taking the snapshot, and after restoring, wait for the clocks on the VM and the host to sync before un-pausing ) Is that cheating ?
