Thank you for playing, I'm glad you enjoyed it! In theory there is a d4, but you have to draw the card that lets you change one of the dice to a d4, and I haven't gotten around to the game simulating a deck, so the cards you draw are completely random, unfortunately. The lack of control is something I've heard from a few folks and will definitely need to think about, even if a little RNG is intended. I plan to keep working on this, hopefully less ugly next time haha.
