Reversiology ⚪️⚫️ https://killedbyapixel.github.io/Reversiology

Play my Reversi game with a built in coach.
u/lewdev

Interesting. Reading through the decisions I could have taken and why another move was better in just one game probably made me a lot better at Reversi. Very cool game!
u/cantelope

impressive work, but like all your work it seems more of a gesture toward obtaining access or status than contributing something of value. the game shows off your skill, but is un-fun to the point of being insulting, literally telling the player how badly they suck. I could not play more than 2 games. I hope you find what you need
