This is an incredible work on the world and visuals for a gamejam. It really made me feel to play more and explore it. However, in the end I spent a lot of time running but not finding much :D I was fighting two enemies after entering the portal but then somehow I was teleported back to the beginning and thanked me for the journey. So I was not sure what I am supposed to do but I had some fun in exploring the game :) Thanks for this submission!

Thank you for playing! Great that you explored some of the remnants. Did you watch the crystal? It tells you when a gate is near.
More content is being prepared. When you were teleported back you obviously (and unknowingly) activated the personal portal rune which brings you back to the tower of your mentor. It is described in the dialogue, a note on the wall and in the help page.
I am glad that you had some fun in exploring the game.
