This was a pretty high quality jam game! The gameplay, art, audio and level design were all well-made. I liked looking for hints for the portal to take, but wish the hints were a bit more subtle. Not sure how the ending went though, I went through the portals according to hints, but ended in a loop where I repeatedly met myself from the future. It happened a few times and then I got the ending after talking to my future self. Maybe there was an extra hint I didn't notice. Oh, and the credits scene didn't seem to have any other text than "Special thanks to".
