My design choices and visual approach – right-hand-side flyout menu, and WebGL video and so on make accessibility harder to address competently.
The design is computationally heavy but I’m betting on moving with the future where GPU power is radically increasing and playing a more important role, and where virtual spaces will become more common.
My design choices make some SEO a little more difficult.
Even my highest quality moon has an obvious-cut-out I did in Photoshop … made a mess of the feathering … and I’m now using one 300+KB moon.png for all devices sizes / speeds.
Even with average FPS testing, on slower devices, some synchronous functions e.g. generating and adding new assets to the scene, can cause brief glitches in FPS WebGL rendering.
