I did a load of work last night implementing the text entry controls.
They'll be used to unlock the shareware version of the game.

I was thinking of some complicated "stop people playing after an hour" system, and prevent them from re-installing to get free time and so on.. but I thought about it and I think I'll just offer the 1st 4 levels for free, after that, the trial version opens the register me screen, once registered they can continue from where they left off. I think the 1st 4 levels give people a good opportunity to see what the game's like before they hand over the small amount of money required to play the full version.

I might add some extra stuff which only appears after level 4 too as an extra incentive.

I'm also thinking of adding a High Score table afterall ops: even after my protestations during the competition...
