This made a lot of good use of the RPG Maker format! It's a good medium thanks to the way that such ambient scenes can be laid out and used - and it helps the writing shine front and center. Kagerou + Wakasagihime is a good choice, as it takes a popular idea into a lot of wholesome detail. Combined with the well-fitting music and cute artwork throughout, it all made for a really wholesome slice-of-life story. Excellent work!
