Unable to progress (Psychonauts 2)

Most of the time there will be a way of progressing through the game which you haven't discovered yet. Make sure you've talked to everyone and explored everywhere, and if you're still unsure, consult a walkthrough to see if there's perhaps anything you missed.

If you are still sure that you're blocked from progressing due to an issue with the game, then there could be a number of things causing this, so the best thing to do would be to contact support@doublefine.com with details of where you are stuck. If you are on PC we might be able to help you with a save file. To help us investigate it would also be useful if you could include your save files in the mail you send to us.
