AHHHHH 💦 This is such a lovely review, thank you so much for writing such a comprehensive one xiongc! 
I'm so happy that your favorite was the UI, haha I'm so honored!! (And yes. . .unfortunately, we noticed the unclickable Quit menu a little too late HAHA! But we have fixed it for the upcoming update! :3)
And I completely agree - we could have done a better job introducing some of the mechanics in the game (like with the slimes)! ^ ㅡ^ We hope to do a better job next time!
Thank you!!
