If you change it from Brotli to Gzip, it fixes that 90% thing w/o it being a developer build. Also nice solid overall game. Maybe if you could make it so I could hold down shoot instead of tapping is a suggestion.

"( PS: Sorry about this being a development build. The loading screen would get stuck at 90% if it was not a development build )" You said this, if you go to publication settings, and change the format from Brotli to Gzip, you don't have to convert your build to a developer build. Just a tip for next time.
