Ok we might have something here.
Physics is fun. Breaking stuff is fun. Therefore, a game about breaking stuff with physics is fun.
Controls feel pretty tight. Not sure about air velocity. I think having a bit of verticality would go a very long way in your game. I am imagining hold a balloon or something to make the robot lighter so you can cross gaps. There's lots of potential there for levels.
As for the actual property damage mechanic I have no idea what was "worth" more or less. I think the helper bots were worth a ton and it was fun to mess with them.
I got destroyed when I aggroed the giant block robot that dude hurts lol.
The only bug I ran in to was when I first started the game and I was messing with stuff, I went over to the knife rack and picked one up and the game went into a bullet-time mode? I didn't really understand how to get out of it even after letting go of the knife it was still in bullet-time slowmo until I paused and unpaused and it got rid of it.
Cool sandbox. I am sure you can find a way to make it work as a full product.
