I've noticed that Microsoft's new browser Edge seems to run the Superpowers editor well from both desktop and my Xbox One, but the preview pane/scene editor and etc all are extremely small in height (say 20% or less of the height is used) while the left panel for project files and settings is full-sized.
Other than that, it seems to work great! I am able to build and run the games on Edge (even from Xbox One, with sound, 3D models, textures, and etc all working fine!) but once exported to HTML5 and run from another source, say DropBox, it starts to act up with missing textures and freezing during load on the Xbox One.
Thanks again for this great tool! :D
Edit: One thing that doesn't work on Xbox One (and possibly desktop as well) in the runtime is music, which is probably due to the format being not supported by Edge. Other than that, I was able to play Hunt The Yeti, Murder at the Residence Gudul, and Fat Kevin without any issues (Fat Kevin takes a bit of a performance hit) as well as other examples and demo projects!
