I really enjoyed working on Rollers' Keep, and learned a ton doing so. Unfortunately we weren't able to implement everything we wanted, general user experience suffering the most.
It can be hard to see what's going on, and it's impossible to know what each dice does for example. Most dice are missing their special functions, but some do special stuff, for example
Forest Dice: worth 1 or 2, but face value +1 for every other forest dice
Snakeskin dice: face value 1, but multiplued by the number of other snakeskin dice. (Could synergize with dice that increase face value)
We plan on continuing work on Rollers Keep, I spent most of the jam building a really modular system for adding dice, so its actually very easy to add more with special functions.
