The art shown here, and concept as described on the game's page is exciting and compelling!
I wasn't certain how much of that was implemented before the end of the jam, and wasn't able to work out how to fulfill any of the objectives. I was able to execute the special abilities described on the game page, and I was able to walk around to temporarily reveal blue tiles. If I went too far away from the blue tiles, I would eventually be eaten by a large mouth, but other than that, I couldn't find any active or responsive elements in the game after 20 minutes or so of playing/exploring.
If I've missed something, I'd be happy to take another look, but if not, I hope that you're feeling positive about what you were able to accomplish and what you were able to learn from the experience. If you continue working on the project, I'd love to see more!
I imagine that you've chosen to distribute your game as loose files to reduce the amount of redundant uploading you need to do. In principle, packaging platform-agnostic data separately from platform-specific binaries can be a good idea, but it has a number of disadvantages here. Itch isn't set up with this in mind, and users running the Itch app will only be presented with the option to install one file at a time (switching to a different one will remove the currently downloaded one). Loose files downloaded via HTTP/HTTPS also cannot preserve executable permissions, but zip or tar archives can.
My recommendation would be to upload all the files necessary to run the game within a single zip archive or via Itch's upload tool Butler. You could include both Linux and Windows executables in a single archive if you wanted and mark that as being compatible with both platforms, but most people seem to prefer separate downloads per platform. Hope that's helpful!
