Pause screen implemented! (exciting, right?)

So, I got the pause screen implemented in game - not entirely sure if it works on all resolutions, but it's there and I've got the idea of how it's supposed to animate, down.

Not the most exciting of updates, but I mostly like how it turned out :)
As always, there's a bit of a discrepancy between what I'd like the effect to be in the best case and what I achieved, but I guess that's normal. Maybe I'll polish it up a bit more another day.
