Basement Challenge Room?[]

Is it true that the flies and the pooters spawn together in the challenge room in the Basement?

I can confirm it, whenever I take the item in the challenge room in the Basement, the first two waves spawn at the same time.

Factors that open Challenge Rooms[]

I find that Challenge Rooms are often closed even if I have full health. I'm trying to figure out what the pattern is, but no luck yet. Maybe I have to clear a room at full health? Maybe I have to clear a room with full health & without a full item charge? Can anyone else confirm that they've seen a Challenge Room closed when they've had full health?


Make sure you're not mistaking the Challenge Room with the Boss Challenge Room. The Challenge Room will only be open if you're at full health. The Boss Challenge Room will only be open if you're at 1 or fewer red hearts (1 or 1/2 heart left, or 0 when you're ???).

Also, please don't forget to insert your signature to facilitate discourse. (Something that I forgot too - whoops)

Spawning two or three waves at the same time[]

I don't really know if this even worths a comment, but say it just in case. I think this is a bug but it could be intended to be like this.

If you pick the chest in the middle of the room and immediately you press ESC to open the menu, you'll hear the "spawn" sound three times-- all three waves of enemies will spawn together. This makes the room incredibly difficult at later levels, but in the first floors where enemies are easier this could help to finish the room faster. -200.120.169.166 15:25, September 9, 2014 (UTC)

Telepills[]

Hey all :) I don't know how to write or explain it but... I opened a chest in a Challenge Room, and got two pills. Enemies spawned while I used the first pill: a telepill. When I reentered the room, the typical Challenge Room music still played, I picked up and used the second pill (health up) but no enemies appeared! This last part is the thing that leaves me amazed --LordRemiem 19:42, November 7, 2016 (UTC)
