Very nice idea and concept, reminds me of the Fran Bow mechanics somehow and the whole changing states to complete the challenges, although I had trouble when it comes to gaming. I barely made it to level 3 haha. I'm aware this can be a me issue but moving was the most complicated, since the ghost is very fast and sometimes didn't follow me or i had issues with the objects, I also missed soundtracks. The idea is very good and I wish i made it to other levels haha, i really like the puzzles and the logic you need to have when it comes to passing walls and interactions like running from the ghost, the objects interactions also adds a lot to it. Keep going!!
