OK, I bought a copy and gave you an additional $25 tip for going as far as
considering people with color blindness. However, I have some comments on
the business side of the campaign. In the UK there are gratis government
funded courses (one night a week for six weeks) on starting your own
business. These 101:s cover all these basics. Get on whatever the
equivalent is in your geography.
So: You're selling on features, which is known not to work well, rather than
benefits as you should do. Nor are you being persuasive in your text, nor do
you have a clear USP (Unique Selling Point). Thus some of your points would
be recast as:
Rather than the defensive 'Not a Fork of SuperTux' - "ReTux is an entirely
new game, using those SuperTux graphics you so love."
"All new game play inspired by Mario[tm] games."
"A concise pro written Python game you can hack to your heart's content once
you have played the original copy and make as many more new games as you
want."
You've said elsewhere here 'depending on how much the graphics cost' or
similar. No, you should have done your research and have a pretty good idea
of how much the graphics will cost in your business plan for this campaign.
As guidelines from 'I am Mongoose So Can You' the 2009 going rate for an
original quarter page professional graphic (predominantly from Brazil) for
pen and paper roleplaying games was $20-$25 *with all rights* (i.e. the
copyright etc all the purchaser's). Around 2012 the best a friend who is a
talented non-professional artist could get was $70 for *all* the art for a
shareware game on the same all rights deal. As in, it looks like the art
costs for this project should be marginal in terms of your budget.
For my money @jxself is right about nothing between the $20 and $495 levels.
One accepted model of becoming a professional musician is called '1000
Dedicated Fans.' A 'dedicated fan' is someone who buys *everything* the
musician does, the musician makes $50 worth of stuff a year and thus has an
income of $50K - costs. I.e. a living wage. Thus I suggest your campaign
should be aimed at milking $50 from low end givers like myself. At the above
art costs things like Stickers, Mugs, T-Shirts, Posters, Hoodies etc are all
doable with a decent profit level in grades up to a $100 perk. I know I
myself like a souvenir.
Anyway that's my twopennyworth.
