At its core (pun intended) a really fun game, albeit kind of super grindy at times. However, there are still some massive flaws which I think need to be adressed in some way before this goes to full release: Finding the Glurch Boss can sometimes take wayyyyy too long, to the point where you probably have way stronger gear than you'd probably need for this fight. Finding the other two bosses (just talking about the first 3 right here) is alright, although finding the hive entrance is a nightmare if you don't have an iron pickaxe yet.
The biggest issue I see right now is that the hive mother seems wayyy too strong right now. When I first played Core Keeper with some friends right after Early Access Release, this was an easily cheesable boss which I guess I'm glad was sort of fixed. However now there is the problem that the boss is just ridiculous in its health as well as its moves (constantly spawning the red, strong larvae and spitting out acid which will stay unless shoveled). Let the fight go on for 30-40 seconds and your entire arena is gonna be unusable. You will either end up dying to acid or be ganged down by those larvae. There's a good chance there's a way to make this fight easier but 10 hours into my new (hard) world I have yet to find the solution to my problem.

tl;dr third boss is way overtuned, devs could consider nerfing it
also the fact that larvae destory torches and will follow a line of torches to eternity should also be adressed like holy crap
