Do you have a list of saved games somewhere, so we can start from where we lost it?
Funny you should ask. We're currently working on a "stash" of machinarium.sol files which players will be able draw from to either recover their progress due to lost saves or directly skip levels that are just too hard for them.
When we're done you've find the stash in the "
Shared Machinarium.sol Files" board.
Meanwhile... patience...
