Thanks for your reply! I'm glad you enjoyed that!

Many people address controls, and I will surely try to fix it when I continue developing. The clumsiness itself is an intended mechanic, but it shouldn't be chaotic. The idea is you cannot un-cut the wood, so you must be careful with wobbly knife not to cut too much. And if you do, you must then adapt and work with a little piece that's left. 

I plan on placing the tool exactly over there point the mouse cursor is pointing at. Also I will make the shadow under the tool sharper, so it can be used as a "crosshair". Or even highlight selected face under each tool, not just marker.

I'm also glad you appreciated  the technical part, I spent a significant part of my time during the jam making all the geometry work. Thanks
