Hi and thanks for the feedback! All of these issues should be addressed in the future one way or another. At this stage nothing is set in stone and a lot of things will change. Hopefully for the better. "Always Run" can be toggled with a hotkey and you can change key bindings in the options menu. propper save function is in the works. AI and movement physics are also under development.
Sword is tricky to ballance. if we make it more powerful it might reduce the usefulness of other weapons. The way it's designed right now is to make the player having to dodge bullets and attacks and not just stand in place when using it. We also plan od introducing some useful powerups that will make the sword more effective in certain situations. Player souldn't rely on th sword too much as this is a shooter game frst and foremost:) Altough there is a lot of playtesting ahead us. If it turns out to be fun enough we might make melee combat a bigger part of the game.
