Awesome job guys, well done. Are you using the Dungeon Crawler Grid Controller from the asset store? I picked this up from a Humble Bundle a while back but haven't tried it out yet.
Have played all the way through and defeated the rat king. You've got quite an addictive game there.
It took a while to figure out what to do at first, you could probably do with adding some help text pop-ups somewhere, just to say "Assign dice to characters or re-roll," in the first phase then "Assign character actions to targets," for the second phase.
I spent my first combat just assigning dice then hitting the bottom right button until something happened, which of course does nothing and starts the next turn. If no actions have been assigned, maybe have a pop-up text "No character actions have been assigned! Are you sure?".
Also, it caught me out a few times when sometimes in phase 1 you have to click the bottom right button to proceed, and sometimes you don't, depending on if you've re-rolled some dice or not. Maybe you don't need the bottom right button in phase 1, and instead just go to phase 2 when all dice have been assigned. About half the time I re-rolled something twice then assign the dice, muscle memory would take over, and I'd click the bottom right button, accidentally skipping my go.
Congrats on your submission.
