Really liked this game! It has a tendency to start slow sometimes if the player and the opponent have similar goals at first, but love the feeling that its a puzzle game where someone else keeps coming in and messing with the work you have done. Especially near the end can get stressful in a good way when you are bouncing back and forth from being in the green.
Took me a bit to get how combinations work and it just felt like my first run was a bit wasted because of this, but did add some nice variety and more depth to later playthroughs. Maybe it would be better if they were explained to the player and not just something you discover, as planning out the space for them really added to the fun. Really good work with the limited number of tiles you did have though.
Overall really enjoyed it, would love to see more stuff added or tweaks to the AI to make it more ruthless
