Excellent presentation and nice take on including the dice. If you did want to keep expanding on this, I think seperating move and attacks somehow (or at least ensuring there's always at least one of each option) would help avoid frustrating RNG. It would be nice to have the ability to change direction, or at least put the tank who can damage adjacent tiles in the middle so they can assist both the other characters.
Still amazed this was done in 48 hours though, nice work!
