Version 0.1.4

This is a smaller update which changes the default control mode to twin-stick, as many people seem to prefer it over the original controls. It also addresses a lot of minor issues which came up during the Steam Next Fest.

• added option to toggle chromatic aberration effects
• changed the default control mode to twin-stick for new players
• fixed single-bullet player-attack doing more damage than intended
• many other improvements and fixes

Thank you and have fun!
