There are issues with saving on some machines. Antiviruses, windows defender and other anti-malware/spyware software prevent the save data from being recorded. We will change our saving system in the future to avoid this bug. Right now, it is a little bit dangerous as we can wipe out the saves of the majority of people for whom the current saving system is working fine in the process of updating it.
We've hired an editor to fix the problems with our grammar. Sorry about that! Turns our English isn't as good as we thought.
Just to clarify: we're a small studio with no one working full time on the game. It's not an excuse. We're determined to fix all the issues soon.
