-Stacking like 10 tiles in hand is both funny and mechanically useful, I like it. Stone cabbages are funny but caused minor confusion for where to find stone for awhile.
-If empty hands are effectively a tool, I think it makes more sense to put a open palm as an icon in the inventory slot 0. Otherwise people may think it's a slot you can fill.
-Tripping/falling after running into something is interesting, the main downside is that it felt too punishing to use indoors. Though I guess you could just make double width doorways for your base and it wouldn't be a problem.
Otherwise the game feels pretty good, not much to say.
