Sorry for the trouble. I just updated the game's page settings (the itchio "Edit Game" page), and I resized the game which should help on lower resolution screens and lower power computers, but also potentially the shop was off-screen for some folks? I also added a very detailed explanation in the game description for how everything works (see "NOTE 2"). I hope that works out, otherwise sorry again. I did test an old intel Mac computer and it was fine as well as my PC with Chrome / Edge, so not sure why it may not work for you. Thank you for trying!
