The score is way too high. I'm doing my best effort and I'm still 500 points away from the goal. The fact that you're forced to get a lesser bonus by wearing the Slayer sword and the Magical armor doesn't help either.

How can i open the black doors or walls or what ever this is. i need the coins in that areas. Thank you for your help.

I was level 11 and having trouble with one of the levels, so I hit the left button on the world map screen to change it to easy. It erased my saved game and started me over. I then finished the tutorial and changed it to hard. It erased my game again and restarted. You have to give us a warning that we are wiping out our current game. Or, just remove that option from the world map menu. There is no real reason for it to be there since we can start a new game from the main menu. ...

I would like a level of difficulty where i can enjoy and progress. Thanks all.

Are the graphics inspired by a certain system? I've read about NES comparisons, which fit the gameplay, but the graphical-style is definitely not NES.
