Good game so far with great potential.
I found some small and "bigger problems" glitches that nobody spoke about before (i think).
First of all, i encountered that the Game Over via the Chaser triggers broken text boxes and can enter a "loop" of showing the Game Over with the (unfinished message about the secret area) before getting into the fight again with 0 princesses left (most i had was 4 times in a row before i got the Bad End Game Over with princess Candance).

I found also that the Drone Controller name can switch to another language in such a situation (hypnod princess + naked + chosing to suck the d*** option)

Shouldn`t a princess leave a battle, if she got defeated, since it didnt triggered one time at the Drone Starlight Boss fight
(And for me sometimes getting the "Latex Drone" Game over is sometimes a long fight, since Starlight should do more dmg in my opinion)

The smaller stuff are, that you have a writing error at the first room/area of the Drone level (where i am also kinda "surprised", that you gave that area a name but not the other 2 areas too)

And i think you forgot to say that you need to press "enter" instead of 'e' in the Game Over screen (since 'e' doesn`t do anything)

Was it intentional, that (some) Enemies can respawn after you fought them before taking the stairs into the next area before going back? (Just curious about it).
Also i am curious about how you would to the Chrysalis level with different changeling ideas etc. (especially how you imagine that changelings could "impersonate"/transform into the princesses in a fight). Since there are some good ideas out there about different transformations into a changeling.
And for a everfree level in the future, i think between timberwolves and the plunder vines, a cockatrice (-pony) or some alraune pony could work too. Maybe some slime enemy from the mirror pond (like slime like copies of the princesses) and as traps to watch out for some poison joke with different side effects (like as example "trance", "low hp/mp". etc.).
Wish you the best for this game and future work.
