Sure! The POC there is simply a quickie tileset mockup using a few publicly available assets. That particular mockup is a platformer, we also used it to test a variety of things such as emitters, collisions, overlaps, framerate, tileset size, updateable fonts and dynamically adding/removing tiles. There were a few tiny quirks, but basically it did just fine. It’s about half the FPS of a modern laptop, but still completely adequate.
That NodeJS port is brilliant, and your thread on setting it up worked great.
The final product won’t actually be using any of these assets of course, merely the POC of using a phaser 3.15-based toolset on GameShell.
For the real deal, we’ll be using those techniques, but I’ll keep the surprise of what it is and how it ties into the space/cosmic theme for later 
/edit For anyone looking for art assets, Kenney.nl is running a sale right now…
