Interesting game, reminds me of Agar.io. I managed to build the version on GitLab, so that’s what I played. While switching polarities to manipulate the dots is fun, the game’s two goals (avoid black + get larger) conflict with each other, because after getting to a certain size it just becomes impossible to fit through the gaps in the black. So eating the dots forces me to lose sooner.
Still, the game is fun, and if the objective was different I could see it being very addictive!
