It's a nice sokoban-style puzzle game with a pretty unique gimmick. It wasn't clear what all the symbols meant at first, but once I figured them out, I think it was a satisfying difficulty for me, although calibrating exactly the right amount of stimulation on level 7 turned out to be beyond me, and when I watched the clear video I felt dumb for not thinking of doing that. Oh well, I had lots of fun anyway. Silicate's expressions are super cute.
I only really have one major issue, which is that the color palette is not very friendly to people with vision problems like me. I recommend running the game with Windows' color filter mode set to greyscale, and then balancing the red, green, and blue tiles so that they're all distinct from the background (and from eachother for colorblind people). If you do that and add a fullscreen mode (or just allow resizing the window), it should be fine. And maybe make the numbers in the vibrator symbols just a little bit larger.
In summary, good puzzle and I love Silicate.
