thanks Geodav 
though i may have spoke too soon.
for some reason if i play on device from the editor everything goes fine.
if i try to package the game for android it crashes for no apparent reason before its finished.
edit:
wow im impressed, 2.2gb for the .obb file 
and theres almost no content…
i knew it would be bad but not that bad, further investigation required
edit2:
manually deleting unused content as well as shipping packaging and its still 635mb…
