Haven't beaten Remilia yet since the update wasn't out but it was super good and reminded me well of Castlevania-like fangames I've played so that's something.
My Old Steam review in beta:
All Right, I have not played Touhou,I have not really played Castlevania(just the nes one a few times),and I've BARELY played Metroid or even know what happens in It even though i should BUT This all changed because of this upcoming game and it's demo.
I had been eyeing on this game for a while looking from the pack that Angels Of Death is in and I was intrigued by it because o knews what Touhou was and had a maid that can stop time like a certain yellow vampire we all know and love :^) and to see that we're gonna get a game that has a time stop mechanic and is going to be a Metroidvania? We'll sign me up OH and look it's on sale, would you look at that hmmmm...Honestly, I'm glad i didnt buy it during that time because i want the full price to go toward toward the Devs to make a great game i can play anyday.It's already gor overwhelming praise just from it's Early Build and has great hour of play time already. This is promising and I hope and expect, great and more

PS- I wrote this a while ago but couldnt post it cus wifi crashed and luckily copied it so I could post It, I am hype for this thing lol
