Thank you! I actually had a lot more content planned but didn't get enough time to implement everything unfortunately (e.g. more dice, enemies, etc).
And you are correct - the damage done is based on the dice roll at least for the D6 and the D8. I definitely could have conveyed that more effectively through either damage numbers or better descriptions in the level-up menu. Something I will need to work on in the future after the jam.
Thank you for your feedback!
