Nice game, though I would recommend baking shadows since that would make the game much prettier! For nonstatic objects, you use light probes.
A bit sad there is only one level though, what you could do next time is to create multiple levels from "puzzles". Just create a prefab that has inside a bunch of objects, and then copy-paste that one prefab into multiple levels. The game might look a bit repetitive but on the other side, you can have this way multiple levels.
