Awesome game..iv finished all the preloaded levels..by hook and by crook, quite literally..

I cant seem to get the user submitted levels to work on my n900 though..from
http://numptyphysics.garage.maemo.org/levels/

The level files are in the nph format (or zipped npz packs) whereas the preloaded level files show as npd in the n900 game folder..

Someone know how to go about this?
