They could of changed a lot of things while still keeping to the essence of the game.
For example, each world has six acts. That's just too many to keep my interest in a place and most of those acts feel less effort was put into them than Sonic Forces stages. They could of at least tweaked three of these six stages to work for Tails. Especially the stages that hardly need boosting.
Eh, I like many acts, especially short ones (usually act 4-6).
I'm too lazy replaying stages that are too long solely for scores, but short ones are okay for me.
I guess people's preference are different.
