the pixel art is absolutely beautiful, and the world is so detailed! It's lacking in gameplay a little however. The collisions were very annoying, as the hitboxes for either the player or the props are much too big. Considering the perspective of your art, the hitbox for the player shouldn't go any higher than up to the neck. It made navigating the world very difficult. The robot pieces need to distinguish themselves from the other props more, as some of them were a little hard to spot. I also came across one robot head that wouldn't be picked up no matter how much I clicked it.
Still though, please don't be discouraged, because your art is amazing, and I'd love to see more of your work in future games!
