Thanks! The earliest version of this game used sliders instead of dragging the parts, but I felt this was more intuitive, and I didn't want to have a maximum and minimum value for either. I don't really get what you meant by “just placing your mouse and left/right clicking”.
I meant more of instead of clicking and dragging the arrow to make it bigger or smaller, I want to be able to place my mouse at the desired spot and click to snap it there. Hope that helps explain it! I just find it's harder for me to be precise with dragging movements. Haha maybe just a personal preference. Cheers!
