Heckadeck: I think the only possible problem is it's proprietary(?) and I dunno what the IP situation is or whether the artist'd be okay with it. I'll contact them and see what the situation is, though. A couple other little things:
- I actually did have zero, one, eleven, twelve, and thirteen, but cut them because thirteen was too long to do the value+suit combos with (for annoying technical reasons)—obviously that's not an issue with Heckadeck since it only has zero and eleven.
- Acorns are actually a suit in German-suited playing cards (see Future Features), but the symbol's very specific (the German suits have a style of their own)—I can work around that with character variants and different-language versions, though.
Rock-Paper-Scissors: I honestly don't know why I didn't think of this! I'll probably do one set of hand gestures and another of objects, with one in the baseline and the other in a character variant.
