Good video pointing out things. (yes I turned on the auto subtitling and it worked well with your speech, it is funny how different it works on different people's talk)
I haven't realized about the night time but you are right. Maybe it could be adjustable. I like both actually. haha. Evening and night.
And as for my own thought.. I know I have talked about earlier.. but please please make the stuff recolorable! Scenery, stalls, rides... that "white half-roof" thing of ticket person is a good example.
It would be fantastic if you can have something that is essentially a scaled down version of Create A Style of Sims 3.

It is quite deep in its goodness, to see how it works if you haven't used it:

Ah I can't find a video that is deep enough to show off its all features.. You can for example drag color dot, texture square or whatever to another furniture to color that too. Drag the whole "tab" (the vertical line with the 4 squares of textures) and it will recolor something else with exact same textures, all of them. You can also make texture custom, if you know how to make, using the 3 RGB channels and the Alpha layers in png to make up for four different colors. It is interesting method.

Here's tutorial on how to use the software to generate a pattern. But I have made using photoshop before that tool appeared using the 4 channels. Think of as alpha layer but four in total. It looks crazy in photoshop but correct ingame.
Something like this but remade to fit the game better plus with feature of adding "decals".... PERFECT!
