do you have the source? Id like to try to package. Itll be everything under the project folder including the .uproject file, you can skip the build, saved, binaries and intermediate floders. your github repo doesn't seem to have any UE project files.
Itch.io didn't tell me you replied!! @_@ It's working now (from what I can tell), because I chose the WebGL setting. You're right I do need to put the entire project into my repo (I thought it was only for the open-source parts)...I'll get to that soon.
