Ive gone into the room that requires the crystals and i am wondering if that is the end. also the other door by the unfinished bridge, can it be opened?

There is no real direction or end of the game yet. It's version 0.1.0, not version 1 or 0.9.1 or something, the previous version was only 0.0.9e - while the process of content might start getting a little easier/faster with the funding now avaialble, it's still really early on.
