Pricing is a tricky business. I assume from your question that you think the price is too high? That's a criticism that others have made as well, and it's a fair criticism, but not one that I agree with. There are similar games on the market which sell for about the same, so I don't think it's an unreasonable price point.
To be fair to you, due to a lack of credit card, low income and Scottish ancestry, any price looks high to me
Having said that, I may tweak the price at some point in the future. In principle, though, if the perceived value of the game is less than than the current price, then I would prefer to improve the game to meet expectations rather than vice versa. So I'm planning to stick it out at $18.95 for the time being.
That's a very good angle to work from.
In keeping with that principle, I will be continually improving Mayhem Intergalactic over time; you'll see from the news page on the website that I've released two minor updates already, which are free to existing customers as well as being the versions that new customers receive. Expect more (and bigger) updates in future!
Good to hear. Keep it up!
