For what it is, it does its job well. A fun little arcadey experience with its repetitive missions, minor story, semi-reliable controls, but all carried by its fun and replayable level design. I mean, other than the fact that its locked behind apple arcade, this game really isn't worth keeping a subscription for. I think this game should've taken the Mario Run approach by charging you $10 for the whole experience since to me, this game is super short and having to pay $6 every month just to keep playing doesn't seem worth it.
If you do plan on playing it though, play on an ipad with a controller if you can, plus use up that free 1 month subscription while you're at it. Otherwise, you wont be missing out on much.

Also no this is not better than Sonic Frontiers.
