First i would like to say, what a lovely game this is,good job!
Ive enounctered some annjoying issues while building bigger creations, it can actually happen with any moveable part, and mostly happens when you have mutliple of the same, one out of X will stop working, you can replace it with the a new ( same) part but that way another block will stop turning, that problem rotates around forver till im sick of trying lol!
Next to that while for example firering cannons , ive noticed they dont fire all at once and sometimes there is a quite big delay between them, this already noticeable with 10 cannons, prob less aswell. This goes for any block actually.
Thanks for your time, keep it up
Ps: increasing/decreasing game speeds result in different outcome which is kinda weird lol
