For a jam entry, this is a solid attempt that clearly had some thought behind it. The idea of playing as a ghost sneaking around your own home is not new, but genuinely interesting, as there’s something quietly tragic and eerie about it that fits Halloween perfectly. The art style itself is appealing, though, as you probably know, the rooms could use a little more detail to make them feel lived in (or rather, haunted in), or they just need to be smaller. Gameplay-wise, the slow walking speed does make things drag a little... It gives that classic ghostly “floaty” feeling, sure, but when paired with the long intro scene, it starts testing the player’s patience before the action even begins. Shortening the introduction or allowing players to skip it would definitely improve pacing without losing atmosphere.I completely get your concept of being an uninvited guest by being the ghost, but story-wise it lands in a slightly awkward place. Since it’s your home and your family, it almost reverses the theme. If, instead, you had been haunting a random family’s house, it would’ve sold that “uninvited” concept more cleanly. Still, the emotional undercurrent of a ghost trying not to be seen by loved ones is actually quite powerful. The lack of music and sound effects is a missed opportunity. A few subtle whispers or soft ambient tones could have lifted the tension tenfold. As for the possession mechanic: Like others already mentioned, if it had worked properly, that would’ve been a great touch. All that said, it’s an impressive piece for a first game jam. The concept is strong, the art and mood are good, and it’s clear you’ve got a good grasp of what makes atmosphere work. Some polish, better pacing, and a more refined take on the story premise, and this could easily evolve into something really special.
