Got a royalties cheque from e23 yesterday, and having done a few sums it looks like Flatland earned about £52 after deducting e23's cut. I've rounded this up to £55 and paid it to Doctors Without Borders; with Gift Aid added it'll be £71 and change that goes to the charity.
I'm nearing another £100 in the kitty for Cancer Research UK - hopefully before the end of the month, if all goes well. Again, Gift Aid will be added to the final total.
I'll post again once this is sorted. Thanks to everyone whose supported my games, it's greatly appreciated.
