Actually I did pick it up, and I also noticed the levels even give you a hint! I think I just got impatient, mostly. Although there's this strange phenomena where cautious gamers will hold onto consumables forever and never use them unless they absolutely have to. I ended up not using the device at all. Partly because of that, and partly because when I first got the device, in the instructions it says to press Right-Click, and I did it before reading that that's how to activate the device, not hide the instruction menu, so I ended up using both my charges before hiding the menu. lol
But more than anything, I personally, just get frustrated with these kinds of games too easily. It's nothing on you; I'm just ADHD and impatient. But I can still appreciate the clean and design and well crafted aesthetics, especially given the short development period. :3
