Just play Sonic Dash. – Sonic Dash 2: Sonic Boom Review

To start, the game isn't bad--it's pretty fun. But the game is just... a watered-down Sonic Dash (the original mobile game). It doesn't feel as fast, there's not as much content, such as no boss fights nor chompers (which are replaced by some rails {that you can find in Sonic Forces mobile anyways} and tilting gimmicks), and the levels are just so empty and repetitive, including the fact that there's barely any gaps in the terrain and no hills or loops. Also, getting characters is a PAIN (a very long grind for some special abilities that barely matter), and the only fun things ('events') are locked behind tickets that I assume you either have to buy or wait for. Meanwhile, Sonic Dash is just more vibrant, more diverse, more challenging, less grindy, and faster (which is the entire point of Sonic), and it has actual seasonal events for cool skins. It also has an additional house-building mechanic. Overall, don't play this unless you REALLY enjoy it. Play Sonic Dash instead... ... Oh right, those sprites that the Apple editors cherish so much. Well, they boost specific things, which is cool, but either cough up the cash or wait a day to get one. Did I mention they're only a one-time use?
