Nice, feels a lot like an art exhibition! The story is short and simple, yet complete, which is nice. A few problems/suggestions (which you might already be aware of, but I’ll include them just in case):

• The downloaded archive only contains a windows executable, better not mark it as suitable for linux & mac
• Camera seems to jitter while you’re flying, as if you we doing some fixed increments to the vertical coordinate
• Flying mode only gets enabled after holding [Space] for about a second, which feels a little bit awkward, maybe just start flying immediately?
• Shadows look blocky, as if in basic shadow mapping or PCF. Maybe increase shadow map resolution, or use cascaded shadow maps / variance shadow maps?
• The “Creator” button looks like it doesn’t do anything; only after closing the game did I realize that it opens a browser page

Anyways, good job!
