Great suggestion—thank you so much! Yes, we actually considered the kind of big nail interaction you mentioned. That’s why we specifically designed every portal so that players could backtrack if needed. In the current demo, there are only Level 1 and Level 2, but our plan was to introduce this mechanic in Level 3 (along with other nails that would serve different puzzle functions) to create a more advanced, large-scale puzzle-box experience. However, due to the time constraints of the game jam, we had to cut Level 3 to meet the submission deadline. We’re really glad to hear that players like you are looking forward to more challenging puzzles in the future!
