Hey Everyone, The beta branch has been updated to 0.6.23 which now features the much requested mouse input options, separate fire/lock-on button option (which also doubles as a rapid-fire option when enabled) and also the initial efforts for Steam Cloud save integration (only the game progress is saved, config data isn't saved as this is generally different for each system you play on). We've put this build on the beta branch as we'd like a bit more feedback on these features before we put it on the main branch. If you'd like to test it out, you can go into the properties of the game in your Steam library and select the beta test branch under the 'Betas' section. Let us know what you think either here or on the Steam forums. Thanks!
