Cool game, inventive puzzles with main mechanic of switching character. Loved that! Nice atmospheric music! Wish there was a little intro in the game telling me where they are and what happened, showing me the connection for motivation <3 The story is strong, making them come together.
Somebody tell one of them to go through the portal themselves instead ;)
One bug that happened in the second puzzle is I managed to get an item stuck behind a portal. I pressed Q by the portal and on the ladder at the same time and then that happened.
