I played for like 30 min and reached like Floor 46, the core game loop is plenty strong, the only issue I did have was that I felt the game was progressing pretty slowly, considering the amount of Floors I had went through. And then I realised I was Stupid.
It took me till Floor 36 to realise that the base pickaxe could be Upgraded and that only happened when I was trying to get the Stronger Pickaxe which needed the base one to be Max. I have no idea how I missed that, but would definitely helped the feeling of slowness I guess. But also it does mean that not much options exist to feel like there is progress being made. To be fair, I imagine more things would come up later as well, but maybe some of it could come sooner. Just a thought that one.
Other than that the Game feels pretty nice overall, and all the quality of life features are great too, wouldn't have played the 30 min if it didn't have the Hover option. The Game also has all the Juice options an incremental game like this would need so that's all good too.
Also I read this being a thing related to Metal Poisoning and so maybe then you should go even deeper into the surrealist nature of it, that would also give the Game that unique identity it needs. Maybe that does happen later on already so don't know about that.
