Probably some people who played latest Len'en game might thought that Unreal difficulty wasn't that unreal like it sounds and could be more challenging. "No way, that's absurd!". Yes, it is! It's Absurdly Extra mode for main story

So, like the name implies, this patch enables to play main story with Absurdly Extra's difficulty index. There were some tweaks done for attacks and spellcards (initially some attacks became broken easy, some attacks became broken impossible (even worse than original Absurdly Extra provides), some attacks became broken to crash the game

so numerous fixes were applied to resolve these issues) but I tried to keep alterations to minimum so it's quite close to what ABEX difficulty would be.
Thanks a lot to
gtbot for testing this modification and video preview! Hopefully, we managed to get rid of all (most) issues it has.
In order to play ABEX story, put the patch into game's folder and run it. It will create a separate executable file to play this mode. In addition to that, it will offer to enable practice for this difficulty for all stages if you'd like. To select ABEX difficulty, choose invisible option between Unreal and Easy difficulties.

Have fun! :3
