Yay Farfields! I'm so excited to see a major update and I'm having a lot of fun playing so far! The gimmicks for the new biomes are awesome, at first I didn't understand why I was taking damage and thought it was something I couldn't avoid, but it turns out you can :)
Spoilers for Farfields below!
As for feedback on progression, so far I unlocked the first Farfields stamina and power upgrade, no big issue, also got the jug and growth hammer, both of which are super fun when paired with Fern (who is currently my main turtle for exploring deeper). The deepest I've reached is the refracted light layer, but I haven't gone deep enough to see a single opal (which I assume spawns in the mentioned layer), so I'm thinking I'll unlock more features from chests etc to get there more easily. Hoping I unlock some footwear soon, which I assume might do something about the mold/venom/gravel. I think they're really neat mechanics, and I like that you let us figure them out through trial and error. I was bruteforcing my way through the mold before finally realising there's a dig pattern that can avoid mold damage. Healing cells cancelling the venom is also a nice touch.
The consumable hammers are really necessary so now I'm quartz poor lmao. It's interesting to choose between which consumables to bring. I also like the function of repairing equipment mid dig, it makes me be mindful of how many smelted bars I need to have in my inventory.
PS: I wonder if wool from sheep use the same spawn mechanic as leather? And I haven't gambled yet, but do the new resources show up there? (Or is that something we find out ourselves?)
Minor bug: I think the icon of anthracite doesn't show properly in the stats menu mid-dig. No other issues spotted so far and the game is running smoothly!
Overall, I'm super hyped about what I've seen so far and I want to reach the bottom! And figure out the unmovable boulder. Thank you for all the time you put into this game, the mechanics are thoughtful and challenging! :D
