Hey,

I've just push an update to Son of Scoregasm which should hopefully fix a few issues that have been reported, such as:

Impostor ship disabled in tutorial
rumble now has a scalar rather than being on or off
easier to see which characters are selected in name entry screens
mouse scaling will default to a higher percentage (it'll move faster!)
traps disabled after level is completed to avoid erroneous achievement awarding.
more!

I've also added an Easy difficulty mode, which you can select in the difficulty menu on the map. In easy mode, enemies are a little slower and shoot less often, however they score half the points of normal mode.

Have Fun!

Cheers
Charlie
