Have run through the game a 2nd time now. Got all the globes on every level. I think i found all the secret areas too  although ill admit to looking up how to get to the top of level 13 (probably wasnt going to figure that out very fast).
Finished the game with a score of 502 although i am not sure how its calculted. The first time i got 94 so a bit of a step up. Anyone need any help or have any queries with anything? What was your score?
The score at the end of the game is just the treasure you have left over. So if you want to score highly, you can try getting through without buying much stuff from the shops. All of the bosses are beatable without buying any potions.
You can press shift-H to view the scores from the title screen (undocumented feature).
I left it this way thinking that for all the players who don't finish the game, it's a bit weird having a highscore table sitting there that you can never use! I'll add a highscore option on the main menu which shows up after you've clocked it though.
