Hey, I just played your game :)
I've been surprised by the dot texture / filter that is hard to handle in fullscreen with a big brick on front view haha
Otherwise, I'd have appreciated a key to rotate the selected brick, I wanted some fantasy in my pyramid :p
I liked the sounds to tell you when you take then take off the brick you select, nice helper. The pysics are good, but the camera / character lacks of frcition meaning you slide on the ground after walking a bit, and I made some bricks fall due to this slide ^^
Finally, a little background music / sound would have given some deepness to your work, but the simulator is here. Just sad to find that we had a place to settle our pyramid and make it fly while I've done mine in a black space near the spawning point :p
Had fun building, thanks mate !
