This is an interesting game. I like the idea behind the tiles changing gameplay, and also the direction-based tile effects like the backstabbing. These are all fun mechanics that are seen in mobile strategy games. The AP system was a good addition to the game as well. The resource management added more required thinking from the player. There is also a good number of things here that you could scale up into a portfolio piece as well, such as procedural levels, and different enemy types, and more characters for the player. Nice job!
