This is great. I haven't been playing many shmups since rabbit & steel came out (and I haven't played TH6 in years), so it was so fun to get back at it. Nice references to spell cards and some fun new twists too. Normal mode is pretty easy (but good and fun!), but I think that's appropriate for fan games, and there is always Hard and Lunatic.
Laevatein killing you if you try to circle above Flandre is kinda lol when going in blind, but I can respect it. Everything else was very intuitive to dodge.
