Performance is not very good. Games like these should calculate the physics of water and sand as larger chunks instead of each pixel individually... the idea is very neat, though, having to dig for gold. 

I wish I didn't knew it is vibe coded. Also, I am pretty sure that the music wasn't in the original version, besides being actually terrible. The graphics are nice. Sadly the performance is a lack luster and I can't even play it properly on my actual gaming rig.

The game seems like a particle physics Spelunky or Steam World Dig, which I think is a nice idea, which I wish would have been executed bit more performant to be playable.

Very impressive tech!
