A fix to the glitch...maybe
First of all, let me say that I think all of your games have been great! They make you think in ways most video games don't or just plain fun!
As for the glitch people keep talking about where their game freezes up when they exit the shop, I had that happen to me. Everything was frozen except me. I couldn't collect coins and I couldn't re-enter the shop. I jumped around for a while, thinking i dunno what, but then, when I jumped into the coinblock from underneath it, as if I was trying to get coins from it, my game started back up. Everything was moving again and no more glitches that I could find. Hope this helps!
Keep up the good work!
