Daytime: There is almost a jungle-like quality to this track with so many polyrhythms/polymeters and the heavy emphasis on percussion and high reverberated melody lines. This is a unique take on the pinball idea, but I think that it would make total sense in the context of a game walking through a pinball town during the light of day
Nighttime: This track has a lot more edge to it that industrializes that original jungle-y sound. This pinball game seems a little slower than the daytime theme which makes me feel a sense of ominousness; maybe the pinball city is not very safe at night!
Overall I think your rhythmic and percussive work are the highlights for me in your composition and the more ambient nature fits a city background theme for a video game well. Great work and thank you for sharing!
