It's a cool concept, and a solid puzzle game. I enjoyed it.
Wish controlling the tank and moving the objects were a bit less of a hassle though, found the control inputs rather finicky at times.
I just learned the game is laggy on Firefox compared to Chrome. The input still has room for improvement but it's much smoother on Chrome. Out of curiosity, which browser did you use?
I did in fact use Firefox, so that would explain it.
