Thanks a lot! :D
I hear ya - but the original arcade game (that mine is based on) behaves like this. If you check this video (below), the blocks kinda "collapse" (or drift off the side) as it hits the edge. So that's why my version does it too! ;o)
Oh, I understand you, but in my place it just bounces off the wall. At least it makes it more challenging! Also try to make a minor prize row.
