I had a similar experience when I first packaged a game for HTML! It worked perfectly on PC, but as soon as I tried the HTML version, everything fell apart.
Making this in just 72 hours is genuinely impressive, and it clearly shows the direction you were aiming for. I can see the vision you had for the project. Some developers spend months just to get a playable demo together, accomplishing something like this in a few days is amazing!
I'm excited to see what your next project brings, whether it's another jam entry or something you have more time to develop 😊
