I imported the project with godot project editor and played it. It is ok. The throwing out picked up things mechanic is cool because the player can master it and get more points in shorter time.
Next time I recommend you to export the project using the Project->Export to another directory like a folder on your desktop with an index.html name. That's because the itch.io algorithm for importing zips with HTML/wasm compiled games searches directly for "index.html" file (i also had the issue that the game wouldn't run on itch, because of custom naming of .html file).
