Some time ago I startet a clone of my favorite game when I was young based on the TileMapRam-example.
Goal is to collect as many diamonds as needed (see status bar) to unlock the exit.
A browser version can be found here:

Screenshot:
As the author allowed me to use the original levels (thanks), some of them are included
Differences to the original game are:
-one type of monster is missing, so at least level 14 is not solvable
-killing a monster (by falling rock or diamond) gives diamonds- in the original game they just blow the surrounding tiles away. Will eventually becomes the hard mode.
-doors can't be deleted by killing a monster - this sadly leaves other levels unsolvable.
not to do:
-New monsters
done:
-fix level14
-doors are always visible and can be deleted
-saving costs a live
-fix bug: monster do not kill you if they are looking for new direction.
-unlock level by level.
-more levels by including an unpacker. (LZSS or rle+huffman)
-player-sprite
Button C gives a little menu. If you get stuck, button a is the "killswitch". If you're dead, button b is level reload.
