This is generally a neat idea well executed.
I finished one run. I didn't let the egg hatch, or encounter any secrets.
Bugs:
I died out of nowhere to a fanatic when revealing a dark room. I'm aware that the trigger for revealing rooms is 1 step further away (it triggers when you're adjacent to the invisible thing that the weapon detects as a target?) I may have pressed forward one time too many, not sure. Or maybe the fanatic exploded early because they were stuck, and that detonated an explosive barrel or killed me directly somehow????
Sometimes the dark room revealing wave doesn't spread to certain places? Like it's blocked by objects or enemies or something.
Criticism:
The water level is a bit unpleasant to look for loot on. Might be intentional that it's hard, since it's cluttered and similar color to loot. But it wasn't really hard, just unpleasant.
The floaty guy boss seems pretty cheeseable, I easily stayed in the first phase long enough to get a decent amount of ammo.
I didn't really find much use for the syringe.
I think the new buried laser enemy mostly makes the game easier since you can run them out of ammo and you can bait them into shooting each other for loot.
I only encountered like one witch and maybe three flamethrowers. I like the idea of the witch pulling you into difficult situations, could be neat to have an enemy type or object that does something similar in a more predictable way. Like consumable booster arrows that launch you in a direction when you step on them, that are often positioned to launch you into a room. Or a weaker enemy similar to the witch that just has the pull ability and maybe a melee attack that it can't use immediately after pulling. Or an object that causes you to spawn fire behind you when you walk as long as you're within a certain range of it.
I encountered the witch in a room that didn't have very many enemies, and I initially got pulled up against a wall. So it was a tense encounter because I didn't know what to expect, but ultimately it didn't amount to much. I don't think I took damage. They might be cooler usually.
