Thanks for reaching out. Sorry to hear, that you encountered a problem.
I have to say that you are the first person who is reporting an issue like this. But I'm taking this serious and will try to investigate and reproduce it. For this, I would like to have some more details. Could you be so kind and reach out via email -> kontakt@retroarts.de THX!
Aside of that and the fact that the combat is partially random based, the game is not so hard as some people think. The idea is to build and refine a strategy with each attempt. Personally, I'm able to win about 8 of 10 rounds. Sometimes you may have an unlucky round, but with the right tactic everyone should be able to master the game within 2-3 rounds.
As an idea, try to get better weapons, potions and spells first and use escape! Escape is crucial at some points! Many people ignore that, that's not a good tactic. Every new game should be handled on thinking of a new way. Don't repeat the same tactic. Just to give some ideas about mastering the game without ignoring your save issue. Maybe this helps :-)
