Really liked this game, even though there are so many ads. But I can't keep playing. I have worked on upgrading my flamethrower and now out of nowhere I can't access the shop. Really disappointed as I would happily play a level two or three times to collect more money but now I am just to slowly make it through the snow trying to find flame bonuses so I can just cut a way through the snow. It is painstaking and I am getting bored. Was using this app to relax, it is far from relaxing now!!!!
