Thank you so much for playing!!!😃
The reason for using Shift-Click to place the parts was me not being able to reliably prevent the user from placing the parts under the UI elements. I was running out of time so I had to opt for Shift-Click haha. 😓 I can 100% understand why it can be annoying so I will definitely get to making it possible to place parts with just left clicks after the voting period ends 👍
Again, thanks a bunch for the feedback, really glad you liked it 😊
