I have been having trouble getting 3 stars on angry birds space cold cuts 2-10. I usually watch walkthroughs to see how to do it. However, I have noticed that my personal level is slightly different than all the walkthroughs I've seen. My level has a little block of ice and an empty square on the right end instead of the little cement block and cement triangle. I think this is making it harder for me to beat this level. I don't know why mine is different. I bought this app recently. Could that be the reason? Have you noticed this before?
