Oh, I think there may be a misunderstanding, no problem, I think I should've explained myself better.
About the 1st issue, yes, it makes a lot of sense that wood goes with wood and not with stone, but that's not what I meant.
Basically, the side the player is facing seems to tell if the wood is place or not. When the player is facing left when I pressed P, the player put the wood on place, and the counter changed from 0 - 4 to 1 - 4, when I did the same but with the player facing right, he attacked and the counter remained the same.
I cannot trigger the bug anymore but I swear that when I did, the wood pile was with the orange border. If there was a mistake by my part that I did not understand, I apologize, but I wanted to make clear that I was not confusing the piles. And by the way, I actually finished your game ;)
About the 2nd issue, yeah that's probably what happened, I was just pointing it out in hopes that you take it into account for further projects for aesthetic. Sure, gameplay is the most important part, but visual bugs can also make the experience a little worse. It's like receiving your pizza with the cheese side facing the box's floor. Sure, it does not affect the flavour, and most likely won't make the pizza unhealthy to eat, but it will make a small mess.
Anyway, thanks for answering and I hope this made things more clear, as I said before, I cannot trigger the 1st issue anymore, so maybe it was my fault.
Hope to see more of you in the future, I really like your game's aesthetic.
