Thanks for your comments. If I can summon up enough enthusiasm I might try a few of the suggestions. I have lost interest in it a bit :(
Yeah, you have to keep on top of things. I think this looks worse than it is because of the levels included in the demo. Internally, the levels have various variables that allow you to balance out the difficulty and control how fast it gets difficult. I have a level designer that allows you to alter these to get a nice balance, and in a finished game you would have a progression, with levels slowly getting more difficult.
That is, the game is way too easy, and then it suddenly goes critical and is impossibly hard
