Hello,
I recently tried gamemaker studio and I was able to make a 2d game on it. I was a complete novice to game making meaning no coding experience, no art experience, no nothing. It is rather easy to use if i was able to figure out and make a casual game. Thus, I support the suggestion to try gamemaker studio, you can get a free version off steam that will allow only 5 objects but can give you a sneak peak.
I am currently attempting to learn Unity now . . . the best tutorials for unity are the ones that are made for your brain. How do you know which ones are made for your brain? Keep googling them till you find one that works, the official unity website is excellent though.
Thanks. Sincerely,
Cryomatrix
