When failing at the "memory" puzzle, it (annoyingly) reverts all squares you've discovered so far. When it does so, I guess it must be playing a sound effect for each and every one of them, because after a while I start getting "WARNING: MixerImpl::out of mixer slots!"
Now, this is probably quite harmless. It's unlikely that it's leaking sound handles or anything like that. I'm just worried that if it could actually play all the sounds, the result would get so loud that it gets distorted. But if we want to limit it, it doesn't feel very elegant to rely on the mixer to enforce that limit.
(Oh, about the name of the save game? I'm currently testing The Neverhood in Valgrind. It's tedious.)
