So I've got it installed and running, and it is clear why this is a soft launch. The music tracks change seemingly at random, and the game is very poorly optimised. In terms of the mechanics, rings no longer increase your dash meter. Instead, there are orbs scattered along the ground alongside the rings that do that. Sometimes there are rings which add more to your dash meter than orbs. You start the game with 30 red rings, and after your second run the game forces you to use these to buy a character, of which you can only choose Knuckles or Amy (Tails is worth 50 red star rings, Sticks is worth 70, and Knuckles and Amy are both worth 30). There are three slots for runners, which you can switch by entering a "junction", which is one of the side lanes which branch outwards. When you enter the junction, your multiplier increases and the game lets you pick which character to continue with. The junction continues to lead to a new area. Sometimes a hook-swing powerup appears, which launches the player into the sky where they can collect orbs and rings by tilting the device. Each character has different abilities: Knuckles has the power "Knuckle Slam" which lets him slam into the ground by jumping and then swiping downwards, while Sonic has the ability "Dash Ring Magnet" allowing him to attract rings while he is dashing. There are also "Events" which are similar to the daily challenges in Sonic Runners, except there are multiple different challenges that expire at different times. To enter them you need some tickets, which you have 6 of at the start of the game. There is only one mission at any one time, which gives a set prize when completed. Much like Sonic Runners, the prizes have to be redeemed. You can also rack up combos by destroying enemies (of which some are now flying) and dodging obstacles.
These are only the changes I have noticed however, there's probably many more.
