Secondary weapons are locked by default. The first unlock should come after one play-through while the others might take more time to unlock.
The current guns are locked by lifetime gold so essentially the more you play the more guns you unlock. Guns that come later will have different means to unlock.
I plan on making changes later such as finishing/adding the guns you unlock to the unlocks portion of the main menu.
Styles aren't locked yet because I want to tie them in with Steam achievements. Expect this to change very soon as we move closer to early access release.
I made changes to player movement so that you're much faster while in the air and wall-running.
I ultimately want to make the player fall much faster. Currently this breaks wall running so once I can rework wall running so that it works with the faster falling I will implement that as well.
Basic controller support has been added. You can't use it in the menus yet but that is coming.
