It was nice being able to always play with atleast some light, night is just annoying, it's fun one map or another, but not for multiple hours. If you want to play and join at dusk, you have to play ages until the sun shines again, it takes ages until dawn, sometimes your whole gaming session is at night :/
My Idea:
Remove the hour system, make it a simple Dawn-Day-Day-Dusk-Night-Dawn cycle, changing after each map (double day, as its summer!). So you always get multiple light effects even while playing only a short ammount of time.
