Interesting experiment, thanks. Another artist here on youtube Lena Rivo suggested using Winsor & Newton's Blending Medium to keep gouache wet, about 20-25%. Might be interesting to try that out on the colors that hardened a bit and see if they fare better after the same amount of time.

Thank you for your comment. I'll check out Lena Rivo's KZbin channel. I think art stores sell mediums for gouache, but I wanted to experiment with things I already have at home. I plan to make more videos about the results, so please come back and watch again if you'd like. 😊
