first exit portal is in an intraversable area, rendering the game unplayable.
You can move portal using arrows. Place in which you enter the portal controls difficulty of next level. (Everything is explained in text before game)
But we should probably add explonation also to game page.
Thanks for comment
the way it was formulated made it sound like there would be multiple portals ala Quake 1.
Ow. Sorry. Intro text can be a little bit misleading I will try to formulate something better as soon as possible
