Alisa speed didn't change anything, however I did increase player speed in phase 2 in V0.3, also the delay moves the play there right way (In V0.1 you move random direction based on the last key press) Alisa will be rooted well this is happening.
(the second part) I hope me cutting the timer in half, the level up event is needed as she growth bigger to keep the fight fair. (also V0.3)
Sorry I don't know what event difficulty you mean in what game.
Maybe I can adjust it, if it's the whole game I'm going to introduce a easier mode where the girls won't scale with height. (and maybe remove the lose trigger if you become to small like v0.1) this is currently worked on for V0.4
Sorry again for the bad experience, are you satisfied with my answer?
