Funny that you mentioned it, since I watched entire Jonas, multiple times.
I feel like 3 colors is not too much, it's not like I am using 7 random colors, maybe those colors are not complementary (I didn't check), but I like how they look togetger, and I chose other colors to fit those 3 main colors.
I have never worked with particles (I don't think it would be hard), honestly, can't imagine where would they fit, it's not like birds leave trail where they fly, maybe I could add them to coins or cities, but I don't think that would make a big difference, at best I could make something like explosion whenever dragon robs cities.
I couldn't make better art because I completely exhausted my human limit, as I said before, there were many ideas I wanted to implement, many things I wanted to fix, actually, I wanted to enter WeeklyGameJam, but, it does no longer exist, for some reason, I could only do that much in 2 days, and I also felt ill on 3rd day.
