The game is great, however there are some serious optimization issues, this is the only browser game ever that has crashed my PC.
It seems to be something with the audio? when im in expedtions the audio is very delayed, like its only allowed to play a new sound AFTER the previous one has completely finished playing, my game usually slows down a lot when im in expeditions, so much that even though i should be getting 80 million SP an hour i usually only get half of it, due to how low my framerate is.
The 80 mil/H mentioned is when the "counter" under SP is swinging between 80 and 110 mil/H i just assume its the lowest number.
