i can't really comment on whether this works for tactical minis games but this is very cool. You chose a lane that many micro, mini, lite, ttrpgs gloss over. You get a lot of my respect for doing what many creators should be doing - making a game YOU would want to play and then making that accessible for others. This is so just so stylish in a minimalist way.
And it was very nice of that cat to loan you their dice for you to make the promo images.
