It might not be the most fluid feeling metroidvania out there but the time gimmick really carries this and makes it interesting. It's not very long but it is sitting at a good length in terms of always having new ideas coming up all the way to the end so it stays fresh throughout. There are some extra challenges to attempt which will require a fair bit of thinking in terms of routing to figure out on top of competent play, so there's a bit extra to go for in that regard for challenge seekers.

I'd love to see a sequel that expands on the concept.
