The idea of the game is very entertaining, besides being very beautiful. I ended up having a little bug (where I ended up getting off the screen and falling infinitely into the void), but nothing that would get in the way of my experience. Thanks for the great work ! Sorry for bad english.
The gameplay itself is a little rough, but I like a good physics clusterf**k game.
I think the only "issue" I have is that the railings are really difficult to get around. That and maybe lower the "ceiling" so that the ATM isn't floating around.
Also, sometimes the ATM seems to just *pop* back to the floor when going from Smash mode back to walk mode. Not sure whether it's an issue.
Also, the symbols above the 'customer' heads don't make a lot of sense to me.
Otherwise, I dig it a lot!
