ok, i'm prepared quick and dirty way to draw a custom levels:
http://www.retrosouls.net/zx/!glufCustom.zip
There is no special level editor and i'm use a charPad from c64 world.
How to make levels:
Run
CharPad, go to
options->Color Palletes->ZX SPECTRUM
Open a
baseNullLevel.ctm file and save it with
levelXX name. don't forget to type .ctm extension manualy since there is charpad bug
Draw an level
Go on
FILE->EXPORT DATA check only
MAP and save as
levelXX.bin
Run
build bat and there is a gluf.tap with your levels
Since a charPad is an universal editor drawing a levels has some troubles and i not remember all of it
Here is some tips i still remember:
On the first level there is no enemies since GLUF letters uses an enemy sprites
No more than 32 elevators, if platform splits an elevator it must be splited by special CROSS tile 40
as in !splitElevator.ctm example
red ghost tile it's a ghost respawn points, it must be 4 on level if there is a ghost
arrows tiles it's a waypoints for flying enemies
when an enemy collide with waypoint it randomly gets an one of directions
be carefull if flying enemy try to move off screen it resets a game
door tile not used since a door always appear at enemy start point
no more than 4 enemies on level but i recommend 3 to stable gameplay
good luck
