What do you think of Touhou Artificial Dream in Arcadia?

It was like first released as a demo, but now at this day (or at the current time when it was released), it was fully released. It even stars Touhou's best girl and waifu Sumireko, sooo..... What do you guys think about Touhou Artificial Dream in Arcadia?

There's also this game called Udongein X, and it's made by the same creator. No thoughts on how I explain it but it's literally a Mega Man X and Touhou fangame starring Reisen Udongein Inaba.
