Cool game with a lot of potential, i like the idea behind and the art direction.
I have a hard time with the UI, especially in crafting. Didn't find intuitive to have the inventory and crafting window opened at the same time, and the way to "retrieve" the item is not clear. Maybe "automating" the crafting process would be cool (without the need to grab and drop the items).
The jetpack system is kind of weird too, i expected to fall when i'm not pressing "W" or "space".
Tutorial text is also not very intuitive, being a overly long info dump. I recommend to simply add small contextual tips and visually highlight the objetives.
You have a potentially addictive crafting indie gem here, just need a rework on UI and UX aspects to unleash it's full power
