Very nice! This one actually made me feel quite engaged. The branching dialogue option combined with the twist made it especially interesting, more so than the more standard games in this jam. The music played into the mysterious mode pretty well- light hearted but a tiny bit mysterious.
*SPOILERS AHEAD FOR ONLOOKERS* My only gripe is that there wasn't some big ending, at least not that I could find after like 5-10 minutes of play. It would be nice to give the player the option to break the time loop and then start a multidimensional war, and then have some positive HAPPY HALLOWEEN on the game screen as everything burns. The irony would be great and it'd also allow for a commentary on gaming, where players feel forced to do everything just because there's an option. You've got the elements here to really construct a good story. You pull the player in pretty well and you've got the engine done, you just need to flesh it out more. Like, maybe members of the town can help with the mystery? I'm a fan of what you had so far and this is probably the most engaging entry that I've played, which I completely didn't expect from the tiny pixel-art candy you have as the image. So, overall, nice work, but please do more along this idea eventually!
