This game reminds me of Among Trees, a game which was a lot of fun but clearly ended development too early. Yes, it's a complete game, I had no bugs, but there were a lot of little things that could have been done to make this game standout more.

Puzzles are used to 'repair' parts of the lighthouse. There are five puzzle types with varying degrees of difficulty within. None are that bad, but if they're hard for you -- no worries, the point of the game is to automate repairs, and you can choose the order. Just automate the challenging puzzles first, and the game will be quite casual beyond.

The "Open World Survival Crafting" tag is a complete farce though. While you can technically roam freely, all the islands and quests are in linear order, so it is 'faux-open-world' at best. It's also not "Survival", as there's not even a health bar. I jumped off the lighthouse many times and took zero damage. Not sure there's damage anywhere in the game? Crafting exists, but outside of a few quests meant to act as a crafting tutorial there was no need to craft anything.

All that said it was fun for a weekend, and it's an easy 100% achievement play through.
