Hello Sebastian. I am thrilled by the game and your channel on YouTube. I don't know why I waited so long to look for it. It is genuinely a fun to play and I'm loving it! There were no bugs that I could see. I'm greatly impressed.
As a quality of life improvement feature I'd like to suggest adding a ctrl+c or ctrl+v feature when selecting multiple chips at a time. If it is easier to implement, an option in the dropdown menu to copy a selected chip(s) and paste them when right clicking when a wire is not currently being drawn. I hope that things are going very well for you and I look forward to seeing where your future projects take you.
