That was my first project beyond very simple tutorial stuff so I'm honestly not too much further than complete beginner myself! I think you should just go for it! Engine-wise I chose Godot because it's open-source and it's pretty simple to get started for a hobbyist like me but Unity is also a good choice due to the sheer amount of support and resources available. I wouldn't stress engine choice too much since many concepts will crossover so you're not like starting from scratch if you decide to change.

I'm happy to help answer questions or give pointers or whatever to get you started if you ever want
