I'm not sure if this is a room type you created, but i wanna confirm if you're supposed to run through the spikes. It doesn't spiral or anything.

The spikes on the right side of the outer circle go down to let you into the inner circle area, basically gotta loop around the outer circle, then loop the inner circle twice for 2 item reward

(Went back and double checked, room is possible at base speed with no flight and no damage taken)

Crashed in scarred womb devil room, which doesn't contain a deal but two 404 trinket and half a heart. I'm not sure it's one of your rooms but should be. Crash when Dark Bum was about to pick it up.

Crash log when trying to continue my save (but it's impossible with all mods, not only yours): https://file.io/U2gNCnQohK0v

I've narrowed down the source of the crash to some jank interaction between dark bum, bone hearts, and not having bone hearts unlocked, I'm looking into if I can fix it

Alright so, after crashing my game another 20 times my conclusion is the following:

When a gold heart or bone heart spawns in, and you don't have it unlocked, it turns into another random heart. If this happens in the devil room, and dark bum picks up that resulting heart, something something isaac programming magic, game has a stroke and dies. This doesn't happen in ANY other room type for whatever reason, so I'm just gonna remove the bone hearts from the 5 devil rooms that have them and replace them with something else.

Issue shouldn't happen again once this next patch goes through

Bug?

In a super secret in Cathedral, I
------- HUGE SPOILER ------


unlocked Dark Judas. Is it a bug or was it intended? Good suprise in any case, and it doesn't seem to interfere with unlocking of alt paths for now (which I haven't yet).

Rare super secret room variant, intentional

I found a secret room that apparently uses all top and left as an exit, but right also was connected to a room.Is this a known bug? The seed I used was 1QDH 0K8V and the room was on Flooded caves 2, if it helps for checking it out

Hello, which character and difficulty were you on, that's needed for the seed as well! It sounds like the room was intended if each exit led to a certain portion of the secret room but I just wanted to check to see which you were talking about

Crashed in a devil room, which I think is one of yours but I'm not sure (I deleted the other special room mod anyways since yours is way more interesting). Maybe same problem than before, related to not having hearts unlocked? I happened to have Dark Bum this time too.

This game is really obnoxious sometimes lol

I'm looking into it right now

Issue should be resolved next patch.

Issue goes like this: Dark bum sees "random heart" pickup, picks it up, something something programming magic, game dies.

some of the new item rooms and deal rooms feel very overpowered, for example I just ran into an item room which just gives you 4 mega bombs for free? as well as a few other rooms that just straight up give you multiple items. Absolutely love the mod otherwise, the creativity of the new rooms is great, just feels a bit cheaty at times

The mod has somewhat of a balance between stronger-than-usual rooms, as well as worse-than-usual rooms. Depending on luck, item rooms can contain more than 1 item for example, or contain threats or no item at all

However devil deal rooms added by this mod in general have more items in them because of how useless repentance made them, and it gives more of a reason to actually enter them instead of going straight to angel rooms, since you have a chance of finding an item worth something instead of entering a deal room to find shade, brother bobby and razor blade.
