Thanks a lot!
The teleporter is supposed to head to the second half of the game, another floor with different enemies and a final boss (all this was actually finished during the jam, but unfortunately can't be accessed right now - it can be accessed with modding tools if you're so inclined, even).
I'll be uploading a bugfixed and improved build after the ratings end, so if you're interested in finishing the game properly feel free to give it a try then!
