I want to play with Seiran, but without losing my save with Reisen. It's possible? Since the game doesn't offer save slots, I would like to save my progress with Reisen and then delete my data in the options menu. That way I could start a new game with Seiran. So whenever I wanted to go back to Reisen I would just put the old save in place of the new one. Does anyone know where the save folder is on the PC?...

I'm trying really hard to figure out what you need to do for those two challenges, but I just can't. Has anyone managed to complete them? So far, I can do Shining Needle Castle in 6 flips, and I'm not really sure what I should do to cut the 2 extra flips. As for the Elixir, the only hint I've found so far is it's supposed to be in Mokou stage, but I've been looking everywhere....

Not sure if I'm the only one, but my controller just won't work at all with this game

I don't know if this is the appropriate place to raise the issue, but I'm encountering an issue with one the skins. After reaching a streak of 10 wins in the Survival mode, you unlock the Color 12, but if you play and then come back to the options, it will be locked again. You can unlock it again, but the issue will occur every time. Am I the only one facing this issue?...
