Game development advice

Hi guys,so i am new game dev who decided to make games cuz shadow slave doesn't have any and thats a crime, i am basically training in Unity (still a beginner though), initially it was a 2d first project with sprites but i decided to to move to blender cuz of my non existent drawing skills and the fact that its a thing ill have to do eventually and can be implemented early , the first level which would be the demo is fairly simple with 1 normal enemy and one boss, however my problem is that now that i moved to blender i dont know what i want, i will have assets that work for scroller, top down, 3d and etc, nor iam sure if i would make characters chibi or humanoid, so any advices/suggestions will be appreciated
