i've been trying to get my gamemaker HTML game to work on here for a while but it just won't,  im getting errors i can't fix since dev tools are obfuscated with uploading

The game works in IDE, github pages and gamejolt so to even attempt to fix i have to compile/upload it back everytime, does itch have special requirements for web browser games?

My guess is the 403 errors are probably just your game engine trying to load files via different paths and not related to actual game error. The exception on the bottom is probably want you want to focus your attention on: “unable to convert string to real”

Just in case it helps, the 403 error comes from our storage bucket when a file can’t be found, as seen here: https://itch.io/docs/creators/html5#common-pitfalls
