Wow... Just wow.
Thank you. Just thank you. I've spent time and time again going through Rainbow Road titles on Newgrounds. Trying to find one that gave that nostalgic past feeling. Well, yours did it. You did a wonderful job keeping to the soft tone of the music. Staying true to a much loved song. The rain just added to its power. Reminding me of those nights were I would sit and listen to the soft rain land on the house and against the windows.
You put those two sensations together in a wonderful manner. The song is loud enough to hear, while also showcasing the rain in the background. The few touches of thunder also gives it a feel like no other, which is only stacked with the sudden bursts of rain.
Everything, all in all, is amazing. I will say it again, thank you. This is I think the best version of Rainbow Road I've heard. Now with everything being said and done, time to download. I wish you good luck.
