People below are complaining about difficulty being too much when in all honesty, the game is piss easy, which isn't a bad thing, this is primarily because enemies DON'T respawn in rooms, the main penalty for dying is just going to the start and not having any projectiles loaded, which is alright as a penalty so far.
I came to actually congratulate you on having the game really feel pretty fun to control, genuinely, it doesn't feel like it's clunky as it did on release, even if my computer denies me from changing key binds, I can work with these controls cause the game feels like it responds to them.
Now there are a few issues about balance, especially with the spawner enemies, namely that the Egyptian one is too weak to be a threat, but the Military one is quite a nightmare. This is because of the typical enemies' ranges are vastly different, most of the Military girls stay back at around a medium range and attack from as far as well, making them pile on quickly, while the usual Egyptian girl also stays back at a medium range, but only hit at melee distance, making it leagues easier to focus down the spawner and clear the room. There's also an argument about spawn times and how many spawn, but that's more a question for play testing honestly.
Again, I wanna sing my praises, because it was a rather fun experience. I would recommend a "Room Clear" checkpoint system and respawn enemies in rooms that haven't had all its enemies vacuumed up like a hoover, if you read all the way through, thank you for the time, you're doing great!
