Just played through this. I honestly don't know what I'm

>Over and over

You should really have just played the game right the first time, man. For one thing you're not supposed to run through from one end of the stage to the next, you're supposed to search each past stage for Robotnik's generator and destroy it. Don't forget to also play the special stage of each world to collect the Sol Emeralds. Then you can see the proper ending.

I mean, it sounds like it isn't for you anyway, but I thought I'd at least explain why it seemed to short and unfulfilling.

Each time I got the past teleporter activates it would disappear before activating, and there are a limited number of those. Hands tied in moving forward.

Each stage has at least one place you can do a continuous loop, the first stage has platforms that spin Sonic, second has a pinball bowl that will keep his momentum, many others have U shaped loops he go can up and down, so on and so forth. Exploration is the name of the game, gotta use the ten minutes to their fullest. People take the piss out of it being the 'Gotta NOT go fast' Sonic game but it really should be played a lot differently.

What platform are you playing on? I believe the 2013 release cut the time needed to teleport in half, if that's of interest to you.

You have to find good spots to time travel. It's a much more fun game if you explore.

Searching for the generators (and the metal sonic hologram) is a gigantic waste of time.

Once you get all the time emeralds, you default to good ending and good future on every level.

it's a game more for it's aesthetic. Oshima was head for CD so it would make sense and with that said CD is the game that truly defines the kind of atmosphere and style Sonic should be like.

When Sonic 2 was being made Yuji Naka was head of that so of course people would praise 2 for more of it's gameplay than anything else.

Yep, that's pretty much it. You can play EZ speed mode, or tedious past UFO hunt. What they really needed was more incentive to get the good future.
