My HiRes coding challenge

[dr beep]

Having seen WRX1K I was thinking of my own version of HiRes in 1K.

A full screen game with a partial HiRes screen.
By moving a HiRes character in a maze (the Wiwo Dido character from the case of the closing doors) you will move the displaying part of the maze too.
In fact you walk in the dark and you light with a torch a part of the maze (which is the part in Hires).

Difficulties:
the Hires sofar uses 370 bytes, the Hiresscreen 200 bytes and the maze itself also 200 bytes so the entire game must fit app. 250 bytes.
but sofar the Hires screen is moveable. Next to do: display the part of the maze and add the Wiwo Dido character.
