Optimize mode should include rendering less goblins, because if your hermit casts a spell multiple times a second, your Potion Master skill level is very high, and you have the gobgob potion enabled, the gobgobs will cause very intense lag for some people.
For those who can't find the walkthrough:
Although the in-game link to the walkthrough doesn't work, that doesn't mean that there is no walkthrough. Search for "Perfect Balance 2 walkthrough" and you will find it. Hope this helps you guys with that physics pack quest :)
That´s kinda a funny story...
That sound should mark the train getting rid of surplus pressure after the stop. However, I kinda managed to time it together with the water filling. And it sounds like that because it´s made with a free tool that generates 8bit sfx.
