Once again thanks to community feedback I've fixed more things and changed one thing that was asked:
v250130
Fixed a bug where riding the spaceship would sometimes show you at the wrong planet
Fixed a typo with one of the psychiatrist lines
Changed the end part of the rat maze (no more annoying fireballs)
Changed the singing timer so the song you're currently singing doesn't reset anymore (before you had to sing too quickly to finish some puzzles)
Removed unintended interaction from a tree in the 3D gallery
Fixed a bug in the sprite for the flowers in the forest - now it shows the right order to sing
