Interesting concept, but I think it needs a better feedback loop. What about adding something to trick the players? Maybe there can be collectibles that lure the player (each can increase their score). This adds a layer of complexity:
- Player has to think if he/she can collect, increase their score or
- Stop collecting and safe guard on a lower tile (1, 2, 3...depending on the opponent tile)
Well, just a suggestion for the gameplay design, congrats on yet another published game <3
