when I was a child I discovered sonic because I was a big fan of mario, and when I started playing it it was with the mega collection on PS2, after that I always made a game in my head for a new 2D sonic game. Sonic mania is that game and much more. Everything and when I say Everything i mean EVRYTHING is good in this game, it's a perfect 2 hours. Music, Level Design, Concepts; Gamplay, Art style, everything is a 10 out of 10. Yes, it's part nostalgia, but I think if I hadn't play sonic and this had been my first game I would still love it. thank you christian whitehead
