Never mind.
Udo
After some very positive and constructive comments on my Udo demo, I'm feeling a bit more enthused about the project again. That's what I love about this site and the journal - really keeps me going on a project.
I've stopped the water from scrolling in the world mode. I was toying with the idea of having like ground under the water that was static and the water scrolling over the top, but that would be a lot of heavy pixel fillrate going on and would push up the minimum specs. Machines with low end graphics capabilities struggle to render the world map anyway, even at 640x480, so it seemed like a pointless feature really.
As per HopeDagger's comment, you can now exit the program directly from the in game menu (with a yes/no confirmation of course). I quite like my menu system really. It is pretty simple, but quite easy to extend to add new options.
Next priority is to make the sheep die when they land on the spikes, which was a very good suggestion that I should have thought of myself. [EDIT - sorted. Quite easy actually].
Other Stuff
Having my car valeted at the moment. There's a lad comes to the centre I work at and does inside and out for GBP20. Quite expensive, but so convenient since I really don't have time to take it elsewhere that it's worth the extra GBP5. Looks like he's doing a pretty good job so far, and certainly better than I'd do with a garden hose and a portable vacuum cleaner.
Here's a tip: have a "quality" option under "Video Settings". The user can then toggle simple effects such as transparency to his/her liking and minimum specs would remain constant. Game developers in particular will always have to look for a balance between low-end and high-end hardware, and giving the user a say in the matter is a favorable solution.
