Thank you @spongehammer!
...with luck you might be able to pack your " real job " in
That would be utopia, although I quite like my proper job - which equals a dilemma of the highest order. Maybe I could turn my proper job into a hobby and keep my hobby as a hobby as well!
So, update so far. It's going to take me a couple of weeks of work and then I hope to have a demo level 1 ready. Everyone will be welcome to give it a play and pick holes or suggest tweaks and ideas. My kids are great for ideas but some of them are too 'imaginative'... Also, the more I do the more I realize that I've still got left to do, which must then be added to the continually lengthening list of game-play idea additions...
There's no way I could have done any of the animation without Spriter; it's proved to be invaluable because of the smooth animation transitions that would be impossible to achieve between traditional animations (so far I have just under 30 animations and I expect to easily double that number of the coming months). Integrating the plugin was sheer brilliance for C2.
Next planned events: underwater swimming, a couple of extra ways to die and then demo level 1 tidying.
