Really interesting project! I genuinely enjoyed the concept, especially the weapon crafting system. Being able to collect different parts from the ground and assemble them however you want in the editor is such a cool mechanic! I also really like how the individual pixels reflect the condition of each piece, whether it's damaged or intact. The fact that you can then use your creations both to fight enemies and overcome obstacles makes the whole system even more interesting.
My main criticism would be the overall pacing. The game feels quite slow at times, especially during the longer sections where you're mostly just walking around. I think speeding things up a little would make the experience much more engaging. I'd also suggest making the inventory closing button more intuitive, as I found it a bit awkward to use.
That being said, I think this is a genuinely creative concept with a lot of potential. You can definitely tell there's a lot of work behind it, and the crafting system alone makes it stand out. With some polishing to the pacing and controls, I think this could become something really special. Great work, and I'd love to see how this project evolves!
