After getting the hang of moving with the treasure, the game was fairly intuitive and quite entertaining to go through! For the low resolution of the player sprite, I'd use a website like Piskel for resizing the sprite (as well as animations, editing, and a bunch of other tools). For some reason I found the death sound effect kind of funny in a goofy way, couldn't tell you why. There is a minor bug where you can still pick up/drop and move the treasure during the death animation, but it doesn't affect normal gameplay too much.
Overall, the game is well made, but if I had to give some pointers, I'd make the music not restart upon death (as it can get repetitive at times) and I'd add an animation to the wall-hang to add to the immersion. Otherwise, its a quick yet fun experience!
