Great game, Wazzy :) I tried it some years ago without the crafting recipes ...
... and I admit I was lost at how to survive / play this game, but after looking through the crafting recipes with the descriptions of how various block affect each other, well hey, fun stuff!!! Its been my favorite game for maybe 5 days now and I've created a couple new games also because I enjoy the initial exploration and challenges and experimentation of trying different strategies to figure out how to set up a livable base. 👍👍
My initial review, without looking through the crafting recipies would have been a question mark (?), but after delving in a bit deeper ... yes, nice job Sir or Ma'am - fun stuff :)
As an idea for further content, it could be fun to have rather weak bats be harrassments underground ... if course plenty of other possibilities and I am certain there are many mods that can provide similar challenges, but that is an idea ... an maybe also, of course, the rare epic 'Uber Dragon', but those are just some ideas.
