I don't mind the difficulty actually. For some reason renaming the save file to Interruption.sav and enabling the load in the config fixes the load issue.
I managed to beat the game and I'd say the difficulty feels pretty balanced. I just had to make sure to keep Dino away from any enemies as majority of my game overs were caused by letting enemies get too close to him. I wasn't too sure where Leah fit in until I realized in the second battle that you can attack with her from a distance and not take any damage in the process. Spears have good range so that makes sense. All in all it was a fun game but yeah im sure many people would appreciate the bug fix.
