Hey StarDDDude, thank you for the detailed feedback!
The alpha blending with background issue, I can't do too much about unfortunately, it's a limitation of web - but the artifacting I can definitely look into! (Might need an anti-aliasing pass and some form of "nearest neighbour" toggle)
I'll prod around with the anti-aliasing this week, and I'll see about unlocking the frame rate to have as many (or as little) frames as you like!
Thanks again for your feedback!
