Yes - I've had a few reports that it's too easy to play, so I've tweaked the gameplay to toughen it up a little bit. The problem is getting a balance between easiness and game length. If you play it long enough it does get faster and harder to play.
Besides, you are all probably only going to download and play it to test it - for which I'm grateful - though quite understandably you aren't going to play it for long are you? Maybe five minutes - ten at tops, so you would not have got to see how the game gradually gets faster and more difficult.
If I made it rock hard after two minutes of play, then most people would have very short games and get bored with it very quickly!
You need to build up your extra lives in the early stages when it's slow as later on you'll need them.
Anyone who says it's too easy after scoring 10,000 points or more I can take seriously. If anyone still thinks it's too easy, please let me know how long your game lasted before you nodded off (zzzzzzzzz), and what score you got.
