Yes amazing, thank you so much for the detailed reply. I've taken notes. :P
I'd say I've stumbled at the first hurdle this time. GLES3 was on by default and I didn't think about it. GLES2 does not work (look right immediately) on this jam for me, so I might just leave it. Good idea to consider it early in development in the future though. I definitely prefer to have something playable in the browser, as do most players prefer as well. :)
