Can you tell us more about this error? Maybe record a short clip? We're aware of some issues but haven't seen this error during development. Does it open a secondary window with an error msg? Could you take a screenshot with that?
Yes, I had a secondary window with an error but I tried the game again and now it works and I no longer have the problem, what happens now is that when fighting an enemy and defeating him, the room restarts and the enemy does not disappear.
