I love this, but there's a few things that could be better...

So, I really like this. In fact, I made my version of a Bongo Cat simulator before I knew this one existed! It's right here, just scroll down a bit on the site to see the instructions - http://gsrca.de/149876

If you looked at the site, my version has a recording feature, as well as 3 cats instead of one. the multi-cat thing doesn't need to happen, but I think a recording feature would make your version even better! Also, maybe, like mine, you can switch instruments? Like, say, the Piano could be switched to a Guitar, so 1-9 keys could play a Guitar instead? Either way, amazing site!
