Thanks for the feedback and
sorry for the hassle. (New to game jam)
I used this link to export the game as an executable.
At first, tried to upload as WebGL but encounter some graphic issues. I am not sure how to update the game download.
I made a new project and did what you said. Link: https://drakmos.itch.io/betterdownloadcosmicdelive
Hopefully, I did it correctly.
