Honestly a cool puzzle game and very clever.
I couldn't get tutorial to load, when I clicked on play and tutorial. Nothing happened / showed. Included pic of what I see just in case it is wrong. The play box is empty and I just spam clicked tutorial and the up arrow next to it. I am running through a sandbox so that could be the problem.
I had to dial the mouse down 75% (but more when I needed to be more precise) and invert the vertical. Don't know if you are collecting data to see what people mostly use on that.
The hardest part is getting the alignment exactly correct for me. I do get the position but if it is a few pixels out it's annoying. I don't know if possible or if it defeats the game purpose but a snap option / feature when you are in that tiny range would help a lot.
