Can't play this, no PCK file.

I believe most other people are having the same problem.

Unfortunately I cannot try the game on Linux, is it too late to export it for web?

Pack any files created for you game export into a zip and re-upload. Ensure you have both the .exe and the pck file.  Comment on this if you fix it and want me to come back to try/rate it.

Yep, as previous commenter said, the game doesn't run. :/

Cannot open game, .pck file is missing. I know the solution. Its either because you forgot to add it for itch.io accidentaly or you changed the name of the game. If you want to know how to embed it into the game. Go the community page and look for a topic on pcks and debug.
