Update 2

A small update.

-You can now lock your shooting direction while moving by holding down Shift. So for example, you can move left while shooting to the right. Should make shooting a bit less awkward.

-The button for the running upgrade is now Alt instead of Shift.

-Added a credits menu.

-Some minor balance changes.

-Some behind the scenes stuff.

I wanted to add a new level but I'm pretty occupied and mentally tired to do that now.
