Nice job, no idea how to play and don't want to know
To deal with edges
Clean up saw cuts on acrylic with light passes on router table or jointer (just a few thou. at a time) (or you could use cnc like you did), wipe edge clean and fan edge with a hand held map torch.
It takes a little practice, but edges become clear and polished. No sanding needed.
I route the edges with paper on, then remove paper on side I'm engraving and engrave, then remove bottom paper, rinse under running water to clean, then torch edge to polish
