A good start on the very basic stuff so good luck! Especially when working with new tech it's likely more ideal to really focus on one aspect of making a game per project.
For example this jam could just be creating a basic player controller for a platforming world and then don't worry about UI hardly at all and just load players right into that platformer from the beginning. Then next project can be something completely UI based to give you significant focused practice on getting UI controls to interface with each other.
