The game over screen “sass” is basically just something we threw in to amuse ourselves, but I’m glad you enjoyed it as well. ;)
The sound issue is not with the sound effects, but with the code adding too much latency. There’s also a noticeable delay between the game visually reacting to something in the music and the corresponding sound actually playing, for the exact same reason. But that’s something that’ll improve if Ysblokje finds the time for the audio rewrite he’s been planning.
Paddle speed is a matter of difficulty and balancing, which we didn’t really have time for. A jam is a jam. We have plans for some gameplay mechanics that would affect the issue as well, so we’ll be tweaking things anyway. (I’ve managed to juggle several balls for a while multiple times as is by the way, but it’s not supposed to be easy.)
I’ll check out your game as soon as I can find the time, but as I wasn’t the one who actually submitted this one, I don’t get to give out ratings. That’s just how these jams work. Stranded does look like something that’s up my alley though, so I’ll be sure to give it a go.
