On the upgrade screen I was not always able to buy the upgrades shown. It looks like they were showing some I had already gotten, and could not get again. They looked like any other at a glance and I tried to get the ones I thought would be good, only to find out they were not an option. I would suggest not showing those you can't get again, or at least making them stand out as clearly not purchasable.
This was a neat take on the theme. I like that it wasn't just about spinning as fast as you can, but balancing at the correct range. The socks appearing added an interesting extra challenge.
I made it to shift 5 fine, but that one was tough. I really should have used more consumables. I ended up with 2 broken washers and just focused on getting the last one cleaned. When it was, I got the You Win screen. I had expected to need to do something to deal with the broken machines or have lost due to them being broken. My final score was 14,809, with 440 Lint earned.
