Thank you for the super feedback!
The idea to blind the baby or to generally interact with him at the window is a great idea but no here it was simple you have two ends... Indeed, you can be trolled in a third way if you make some stupid craft combinations.
For the free end, there was a little cinematic ready for the end but I was not able to implement it at time, it will be for the polished version after the end of the gamejam ratings same for fixing the bug you faced.
