Regarding the HUD, I noticed it's blocking the view. I appreciate your suggestion.
The idea about game balance is also great, thank you!
I noticed that bullets can shoot regardless of whether the dirt has been dug. Thank you for pointing that out.
Your feedback is very valuable to me, thank you so much!
( The reason there are so many fairies under the dirt is that I didn't know what to add for the game's challenge. XD )
