Really fun incremental! The progression felt a little slow at first, likely due to learning all the mechanics, but once I figured out how the wiring worked it went by at a decent pace.
The linear upgrade costs with an exponential growth lead to a really satisfying point in the game where you output drastically out-scales the upgrade economy, leading to practically infinite growth (if not for the integer overflow.)
I was tempted to restart once my numbers were flipping between negative and positive, but there was only ~2000 left so I manually pushed through
I didn't really find a good use for the magnets, mostly because later in the game they become a lag machine due to the sheer amount of boxes there are, and the wiring mechanic as a whole could have used a bit more explaining (maybe include a little tip in the description along the lines of "Put a goblin on the button to generate power.")
Other than that I found nothing else wrong and enjoyed the process of destroying boxes!
