So, I got stuck on the tutorial, the one with the lever. I felt really dumb lol. I tried every combination I could think of, but it wasn't happening!
From what I could play though, it was fun! I think the whole linking mechanic needed a little more work though, like, I was confused for a bit on how to actually link them (even with the text). You had an unlinking visual, but there wasn't anything for linking. I almost feel like, mouse-clicking after hitting "link key", could have worked out a bit better. But not sure.
Overall though, it fits the theme great, and I may come back to this later if I have time to try and see more of it!
