Thank you so much, I appreciate the kind words and feedback and it makes me feel so good that you recognized my hard work! I also wanna start this by saying that I really enjoyed your game and that I aspire to reach your level one day and I feel honored that you said I should be proud.
I definitely agree with you that the y-sorting of the trees was quite funky, but I couldn't find out why at the time so I appreciate you teaching me :D.
What you said about the UI makes perfect sense, I will try to learn how to make custom UI going forward, especially if it makes my game feel more polished like yours :).
About the sword... I actually made the pixel art for the sword together with the other items, but unfortunately didn't have the time to make its animation; this was a shame because I completely agree that having the sword in place of the bow, and the bow cost even more would give people more of a challenge to work towards!
Thank you so much for playing my game and giving me fantastic suggestions, yet another one of my days made :)
Edit: I would also like to say that I really really want to implement these suggestions and under normal circumstances, I would... but I am back in the military for the next few weeks so I have no access to my pc with the unity files on it :( sorry if that is a let down
