The best game port ive ever played the fact they didnt change the base gameplay makes me so happy on top of that shadow generations extends this game you can litteraly finish in 3 hours and its a banger i honestly see this as a polished product but what quite doesnt make sense is there are levels shadow wasnt in that sonic appeared in i would love it more if it actaully had more involvement in the levels shadow was playable and always going back to a radical highway was overdone by black doom other then those nitpicks it had some of the best level designs ever my favorite being sunset heights and final canyon and ooh the bosses were so good to like biolizard was such a obvious choice but they went further and beyond with him cause using chaos control a move you can trigger if you do damage to enemies when you use it at the right moment when he makes a move you can instantly do it again and may i say chaos control is a awesome speed run time mechanic holding everythins still the time and level and its so fricken addicting you can even acess shortcuts while activated i could go on even more but just notice if you like modern sonic there is definitely something in this game youll love worth playing through everything
