Wow, that's over a year working on this project! That's real dedication! (I've spent almost 6 months on my current game and I'm already feeling like I don't wanna see it anymore lol)
I can feel that the janken was rushed, as it doesn't look as polished as the rest of the game, but I understand, since you've spent such a long time working on it and wanted to get it done asap.
If you want completeness... Don't forget about Holo ID! XD
