Nice start, looks promising, although time consuming
The beginning can be quite a grind - expect a few hours of resource gathering and eyeballing the recipe guide for a path forward.
Like pretty much all Skyblock games, your hand won't be held, so you have to follow the recipe guide and build a strategy on that. And oh, boy... it's not easy to begin with. But once you craft some resources, you can use quicker recipes to multiply them, which is welcome. In such cases, make sure you manage your inventory properly so you don't have to take the long path to getting more of some resource. :)
I found 2 issues, one of them actually breaking the progression at this time. I filed bug reports in the issue tracker for both. The bad one is being unable to craft bronze ingots, which is an intermediary step towards getting a bucket, so you can later get water and lava. So right now making a cobblestone generator doesn't seem possible, and it took me a few hours to get here. :P Ooof, and I was actually close.
Thanks for the game, I'll follow the updates and resume my progress once bronze will become available.
