Thank you, really, that's some deep feedback, really valuable !
Most of the physics issues are already fixed (collision ones at least) and I will be working on the rest, the visual ones like the tools clipping is noted but as it is not game breaking it's lower on the priority list, so thank you for letting me know !
As for your Qol suggestions, most of it will be "fixed" in the full game as I designed the first tools to be not the most reliable and easy to use, so the upgraded version are really better and allow more complexe contraptions building, but I get why it doesn't feel complete right now
