This is prompted by my experience of running OL on a laptop, which ended up showing me too big window for laptop to showcase its entirety.
So either:

• make things in OL game somewhat adjustable to any size divisible by 32 larger than n, or
• make second (third?) resolution, and switch between them depending on computer's screen size

Obviously second is easier, but would still involve several checks, former is more complex and would need to abstractify a lot of things related to rendering, but could actually work better for long run?
