There are some bugs, but overall it's fun. One annoying thing is that double clicking adds as many of the item as possible, so an accidental double click on a power cell means instant meltdown.
Also the Heat Control Operator doesn't work how I would expect. It seems to just turn off heat outlets, making them useless, instead of stopping the passive per tick heat reduction. Turning it on whenever you are using heat outlets means an instant meltdown.
