So, the 2D Sonic series is known for it's various level gimmicks, which usually involve fun creative ways to use or create movement and momentum. Sonic Mania managed to unite a lot of disparate gimmicks and merge them into re-imaginings of levels to great effect, essentially giving you the nearest thing to "best of" levels. If there was a potential Mania sequel, and you had to design a set of entirely new level gimmicks, what would you include? I would potentially build on an Encore mode type setup, and incorporate the "Time of Day" level palette shifting from Knuckles' Chaotix, but in such a way that it could trigger weather effects which alter the layout of the level on the fly. So, say something triggers the season condition "Winter" in Angel Island Zone, given enough snowfall it can block certain routes and open new routes. You could then also incorporate lamp-posts which change the season on you, so you have to be careful which checkpoint you hit, potentially sacrificing a checkpoint to maintain your desired route. It would add a bit of creativity to the levels, and would break it out of the bog standard "Island Zone", "Casino Zone", "Ice Zone" level archetypes that have been done a million times. Entering Special Stages could advance the flow of time so it's potentially a whole different time of day or season when you exit the Special Ring, and the level is adjusted accordingly. This is more of a large scale gameplay gimmick than a particular level gimmick, but I feel it could expand developer creativity with the gimmicks used within the levels. Anyway, to reiterate the question; If there was a potential Mania sequel, and you had to design a set of entirely new level gimmicks, what would you include?
