; we are using a tilemapper (needs to be made still :<)
; level data is stored in bitmaps when compressed.
; uncompressed it is stored in a bytefield each byte corresponds to a tile
; 0 is water normal
; 1 is water ani 2
; 2 is water ani 3
; 255 is lilypad
; 254 is lilypad with frog

; the hud will be drawn inline i believe


; we use a lfsr (because i love them so much <3)
; to choose the levels randomly
; one can choose a seed at the main menu by using sto if they dont one will be choosen randomly
; the levels are stored in the format

; x nib y nib
; bitmap of image
; the frogs starting pos is stored in the nibbles of the first byte as it will never be larger than 8
; every bit set in the level data will be a lilypad not set it water


; lillypads are in dark grey
; frog is in black
;other things are in random color choices
