Block Buster. It has a similar design to the discontinued Hypnoblocks by Ambrosia Software, but the rules are different. In my rendition of the game you still have to tap blocks of the same color to make them disappear, but they are constantly replaced by more blocks, and the time you have to make combos goes down each level. The objective of the game is to tap as many blocks as possible in a combo to increase the score gains before it becomes too hard. It supports multitouch which is useful in the later levels since there's very little time to make combos. Here's a $1 of the game.

I thought I'd have trouble navigating large source files or that I would miss things, but as it turns out neither of that is true. With a decent IDE I can easily navigate source files either by using code folding or an object browser, and I don't always need to read every symbol (when I do I just read character by character).

I'm not using any special tools to code, just Xcode, which is fairly accessible. The biggest problem I have with it is the debugger which is not very accessible even if I use commands, because there is no way to insert break-points with the keyboard and I can't read the debugger's console output since when I try to focus it with the screen-reader it only focuses the input text box, but I sort of get around that by inserting lots of asserts and watching the values when they fail.

Sorry, not for this project, it's too small for two developers, would lead to lots of merge conflicts. I will need help with my next project though, since I'm planning something big.

I'm legally blind so I still have a little usable vision, but I sit really close to the TV and the colours are bright.
