Your "Next" button gets hidden under itch.io "View all by Luca" etc buttons, then the rest of the UI doesn't fit entirely on screen so some buttons don't seem accessible. A little more work is needed to fit to window + all the browser overhead.
Windows + Edge, the issue with the 'next' or "X" button is when not in full screen. In or out of fullscreen the App captures the mousewheel so I couldn't scroll but I see now that there are scrollbars.
