What a wonderful thing!
Accessibility wise, I've been testing out with a few standard and not-so standard accessibility devices. I've posted a review here: http://www.gamebase.info/members/profile/14/blog-view/591
Here's my accessibility wish-list...
1. Start up screen. If you're reliant upon a pointer-based device alone (e.g. eye-gaze technology), being forced full screen, then having the SPACE bar as your only way to progress, leaves you reliant upon someone else to get you going. Similarly, if you're using reduced controls (e.g. two-switches), SPACE is also an additional button that you never need again, which may be one button too far. Would be great to allow W, UP or a left-click as well as SPACE enabling Porteus to get going.
2. Would be nice to have a way to select full-screen/windowed and to choose the game world size using your main in-game world controls (e.g. something to click on).
3. Allowing for an additional control mode where your mouse pointer is visible and not-locked into the Proteus window will allow a user to quit the game who might be otherwise unable to access the ESCAPE key.
4. A pure one-switch mode would be the icing on the cake, as there's only one other game I'm aware of that can do this, called Portem: http://switchgaming.blogspot.com/2011/02/portem.html
- And that's a bit invasion of the body snatchers in atmosphere.
Aside from this, there's so much in this making it accessible from the off. The collision system works brilliantly for people using reduced controls, the control system allows for a lot of versatility in using alternative set-ups, the windowed mode at the start allows you to freely set-up a dwell-clicker. Brilliant stuff!
