This is a neat little crafting puzzle game and i had fun with it crafting many different items. I didnt really reach the end because i wasnt fast enough i guess as the new pieces of junk kept getting in the way haha! The artstyle is quite pleasing and consistent and goes will with the space theme. the items themselves were represented well visually with a clear progression of higher level crafted items.
The controls felt ok, but sometimes the lag in picking up the item and placing it felt a bit irritating especially if the place would be taken up by a new spawned junk item! I noticed a bug where i was sure that i had combined 2 pipes but i got some other combined item. i think if you press space and move immediately thereafter to the adjacent one, the crafted item changes.
The gameplay loop was quite fun and engaging so i ended up playing for 15-20 minutes. However i would have liked to know some progress or how close i was to my goal as i played and the text below helped a bit, but i couldnt really get much idea from that. Also i think the speed at which new items spawned can be reduced a bit.
Sound effects were ok, but definitely would have liked more maybe a crane moving sound and a few more. A nice ambient background track would also help to create a nice vibe.
Overall it was a fun game, well done:)
