MMiaW: Doors

Here are the doors between forest areas in open, closed and blocked state. You can blast the blocked doors with bombs to discover secret stash of treasure chests. The regular doors close when there are monsters on the screen, so you have to beat them to go further. Or, you can blast the door open with a bomb and escape the battle. Beside this, there will be a magic spell that opens doors.

I also plan to add a special Boss door for the boss room, and locked doors for which you'll need a key to unlock. I'm not sure if the shop needs a special door as well?
