I’m looking on the bright side, and I can definitely see the potential here! Having a defined win and lose condition would go a long way towards making this be an exciting game.
Generally, turn-taking games like this one involve puzzle or strategy of trying to plan the best move. If you instead made it a real-time action game, this can make the moment-to-moment gameplay much more exciting and intense. Which style to choose depends on what you’re trying to make and what your goals are - definitely something to experiment with.
Thanks for the fun!
