Pretty fun! I wouldve liked a clear end goal, maybe you have to reach a certain amount of money or craft a certain item that requires a lot of expensive parts. I eventually got bored of it but I think if there were a clear end goal I would've stuck through to the end. Also would like some more items to craft with the more expensive items, I think that would help save inventory space and allow for more cool upgrades. Some ideas for upgrades could be a trash can that lets you sell items during a run (maybe for a quarter of the buying price), a new gun with more range or different type of ammo, a jump item that grants an additional jump before landing per each one that you have, an item that slows lava down during the harvesting phase, and maybe like a boss spawner or something that when crafted brings you to a boss that lets you progress or give you a bunch of money. I think the concept has a lot of expand-ability and could be very fun and addictive!
