The puzzles were quite clever and music playing just gave me the push I need when I was feeling frustrated to see the game through to the end. The last puzzle was quite challenging, but it felt so satisfying once I finished it.
I found this game when I saw your post about this game on the RPG Maker Forum. Based on post you pulled an all nighter. I somewhat can relate to that because the last game jam I participated in I owned on the game until 2 hours until the submissions closed. If you are at all interested here's a link to game I submitted in the game jam I spoke of: https://kazuki-t126.itch.io/the-hearts-fallacy
