Did you take the pill "I'm Excited"?

Your starting pill was most likely an I'm excited pill, which will randomly cause the game to speed up for a bit.

That must be it! I did have an I'm excited pills. Thanks to the both of you

I've had it where I took 3 I'm excited pills in a row and immediately died. Started a new greed mode run and the pill effect transferred over. Weird times.

Lmao that sounds hilarious. I'm yet to try the greed mode myself.
