Level 20 impossible!

An ok puzzler, I played the pc version online and enjoyed the challenge. I passed every level, some of which were really hard. When I saw the app I thought itd be fun to try, and that the levels may be different. It was pretty good, till I got to level 20. Ive spent a lot of time on this level and have decided it has no solution. This is very frustrating cause you cant skip levels, so I cant play the rest of the game. Dont buy this game till they fix it!!!
