Played for about 15 minutes, I would not recommend it unless you deeply enjoy this kind of gameplay.

I think it is too slow. You spend a good amount of time actively playing to pick up resources before they vanish, and then spend hundreds of them for marginal upgrades. There were a few upgrades that changed the gameplay a bit, but not in an impactful way.

The music and art is alright. The music loop seems a bit short.

I am not sure why this has so many upvotes so quickly and so few reviews, it feels a bit sketchy.
