Edit : I can't modify the game. Here is the cheat code.

Since I can't fix your save error, before the end of the jam, I'll provide you with the code to activate the MAna Boost and the Gestation Point Boost.

As soon as the buttons are lit, they can be used without moderation and will activate the various cutscenes.

Please only use them as needed or if you've already finished the game. After that, do whatever you want.

Again, sorry for this error.
