Personally I love the concept here. The control scheme is interesting, makes thematic sense, and for me created a lot of tension. While I disagree with some criticism I’ve read, I can understand why some folks might be disappointed by its minimalism. How I might expand upon this would include ambient sound design to sell the setting and, unless I’m missing something, more hazards and level randomization for replayability.
For the technical issue you encountered, I’ve run into this before too! Screen readers can switch between focus modes. By default a screen reader will present HTML in a document context that has special controls for navigation. What you’re probably looking for is the application role. Toss that on your main <div> (I’ve found that <body> doesn’t work as expected). This lets you intercept most keyboard events without Orca eating them.
Thanks for participating again. Nice work!
