pretty good. I'm not a huge sonic fan, haven't played any of the 3D games. this really is just a simple 3-lane runner game like subway surfers with some Sonic ideas thrown in. spin dash to kill enemies, lose all your rings if damaged or die if you have no rings. it uses these well, enough to make this feel unique and Sonic-ish. There are many ads & microtransactions but it's easy to progress w/o spending money. Wish this was just a $3 game w/ no ads. - 1 star for simplicity, - 1 for the ads
