It's double bag and I think there is step reset but it's tweaked? Someone who knows more will have to point it out. The game's scoring rewards speed so I think it's sort of a non issue.

The core journey mode doesn't just look and sound really cool but also had this thing where it puts on the gas to speed things up then steps back to let you catch up which creates cool moments. The zone meter makes you plan ahead in cool ways and encourages vs like building which is cool within tetris guidelines.

Like in general it feels like the first tetris guidelines game where non-vs play works as both a casual game and something you can be really good at. It probably won't make tgm folks entirely happy but it's not messing around. It's a great game.
