After almost 2.5hrs on my first sitting this game feels like a polished finished AAA game with 0, and I mean 0 bugs. This is an alpha? Amazing jo b!
What I like most, well it's hard to pick because everything feels great, streamlined and easy to use. Building is simple yet fun. Tree chopping is immensely fun due to the way you chop the tree, feels closer to real life than most games. Even the spear fishing is fun and easy to get lost in. Tribe management is easy to use and the UI is not clunky like a lot of games.
If this is your alpha state of the game, I cannot wait to see the finished product. Keep up the great work!
