It's such a great concept that Keine actually eats letters while answering lore questions as a way to power up! I also love the way AI works that each character actually has its personality:
Remilia and Sakuya: Chase you at normal speed like what normal people react when they got a thief at home
Patchouli: Slowly walking around the library just like everyday life
Flandre: Run randomly at god speed like a real maniac
As the dev mentioned in the comments, the key is to direct Sakuya and Remilia in a way that they walk in the same direction so you won't get sandwiched. Although they don't seem to choose optimal paths but follow your path sometimes.
I made it to level 3 but eventually got crushed by Flandre. This randomness is slightly unfair as she actually walks much faster than you and I got here mostly because Flandre stuck at some point and all I needed deal with were Remilia and Sakuya.
For the question part, unfortunately the pacing doesn't really allow me to read and answer the question so I just ended up skipping them. If I can memo all the answers I might be able to solve some Flandre shenanigans and actually progress further.
Overall I love your game and with some slight tweaks this may as well be a full shippable game with a price tag. It also fits the theme the way I didn't expect. Take all my 5-stars on this.
