hi eri, welcome to the forum! if you have any questions about godot, feel free to ask in Help (or if it’s a subjective or non-specific question, in General). we’ve got quite a few godot users around who would be more than happy to help, myself included.
once you participate on the forum for a bit and get promoted to member by the system, you’ll also get 20GB of free space on the gitplace. please feel free to use that for your projects, if you wish.
Are your current projects in unity3d?
