I really like this game, and look forward to seeing what the other rooms have to offer. I didn't see a guide anywhere, but would have really liked one, because it took a lot of trial and failure. By guide I mean like a more in depth explanation of the workings of the refiner. I think Marcopole gave a pretty good one somewhere in the comments.
Another couple suggestions: put the gallery in the game so we can easily see what items we already have created instead of going back to the main menu and then gallery. Also, maybe a hint option, like for a certain task, maybe state what base it needs and also what tier item so we can just cycle through the 1:1 until we find it. Also, instead of trashing the item if we get it wrong, because it seems like the tasks are really particular about what items they accept, maybe just give it back to the player so they don't have to spend all that time getting back to the ultra tier.
Great game though!
