NAL 10th anniversary beta edition

Still a long way to go...

some improuvements, some musics, some sounds.

As the dev goes, player gets more skills, but it has to be integrated into a solid linear progression, wich isn't the case at the very moment. to get along with this lake of lore progression, i've added a portal to the lobby world (the one i start with in dev mode) where you can find 'all' portals that lead to any worlds.

still no end for the moment !
