This is a BF derivative that uses whitespace.

All sequences of whitespace are interpreted as trits (ternary digits) with all other characters ignored/removed. The translation table is below:

WHITESPACE 	= " \t\n"
TRINARY		  = "012"	

Then, the translated code is padded with 2s to an even length, chunked into sections of 2, and interpreted as BF code by the following table:

"00" 	=> "+",
"01" 	=> "-",
"02" 	=> ">",
"10" 	=> "<",
"11" 	=> ".",
"12" 	=> ",",
"20" 	=> "[",
"21" 	=> "]",	
"22" 	=> "G"

Uses a semi-custom BF interpreter in which cells can have infinite values, and there are 1048576 cells.
