Pretty uninspired. Boring hub world, unskippable cutscenes and dialogue. (they do not matter)
Cool idea but at the same time I don't like that you're always underground by default, like what's the point of accessorizing when you can't even see your character 95% of the time? Also why do things still hit you aboveground when you're underground? Ugh, wasn't feeling this much.
The gameplay itself is just fine, I like the speed segments.
