What do I do for the github repo? I followed a guide and it refuses to upload(over maximum file size), tried using git lfs but that didn't work either and I am worried because I would love to get the $100 in the event I make it to the top 3 because it would help getting a Steam page for my game(not the jam game)
let's start with what are you using to make your game?
Git only needs to contain your code and game assets - sprites, textures, models, sound and so on. runing into maximum size issue this early usually means you are adding too much to the repo.
For example, Unity project folder can take around 2 or 3 GB even for samll game but all git really needs is assets folder that can be under 100MB. and I belieave Unreal Engine does this too.
Github even provides option tocreate repo with default .gitignore file template for most popular engines
