Just pushed out a new update via Google Play. After some great feedback, I realised it was quite impossible. This update allows the game to start a little easier, but don't worry, if you get more then 10 it will get difficult again.
Also if you remove the ads, you get 3 extra bonus game modes!
It's available on Google Play at https://play.google.com/store/apps/details?id=com.nellyfish.spikesgalore or via http://nellyfish.com
