I think this is pretty creative! I think the main portal mechanic needs some tweaking and maybe the player could move a bit slower but overall a nicely polished title!
I found it inconsistent at times to plonk a portal on top of the player to teleport them (there were many circumstances where I needed to do this). Granted the portals a large hitbox might alleviate this? Not too sure though.
Ah I see, that makes sense. The thing with the portals is we wanted to make it so the player actually had to go in the front of the portal to teleport, but this perhaps was not communicated well through the visuals.
