v0.3.0 - Random encounters

Hey there!

I've completed another major milestone of this game - random encounters are here!
As of now, those are increasingly tough enemies.
There isn't any backstory, but still, that's the first step toward replayability!
Next goal, implementing upgrade mechanism (or saves)!
