Had fun with this one over a couple of run throughs! Simple yet cohesive art, and let's face it it's just satisfying to knock things over and blow stuff up. Voice over got a chuckle out of me. Was fun trying out the different switches for the train!
Only feedback is that I wish it were easier to grab/knock down things at the edges of the play space (my thirst for destruction demands it), and while you quickly get used to the controls I wonder whether you could simplify it even further and have everything be done through left mouse click and moving the cursor around - maybe you wouldn't even need the keyboard.
Definitely worth a play!
