How long is this game?

[Ane O'Lantern]

I think I'll probably play this but I'm curious how long it is, it's not up on How Long To Beat yet

If you know what your doing, maybe 4-6 hours. But if it's your first time and don't already know the codes, maybe 7-10. I'm just guessing.

It may be a little bit late here, but I've completed the game (getting the true ending) and it took me abt 27 hours to beat (didnt use much help from anyone else lol)
