Firstly, kudos to the team for attempting a turn-based isometric grid game. It must not have been easy to code the movement logic.
I liked the creative concept of switching between layers to navigate across obstacles. The idea has the bones for a turn-based bomberman-styled game.
I was slightly confused about how to progress the game, until i chanced upon the "Turn" button which passed the turn. Changing the visual indicator on that button would help make it clearer (e.g. changing the label to a verb "Pass Turn", making a hover and pressed effect to show that its a pressable button etc).
The other unintuitive areas are explained by your lack of time in finishing the game. I assume in the final product, the player would not have to pass on the enemy's turn, and the initiative will pass back to the player automatically after all enemies moved. It was not immediately clear to me what the Red X's were. Initially i tried bombing them, but that didnt work.
After figuring how to move, i had fun making my way all across the map to get to the HQ! I was gleefully about to press bomb, but for some unknown reason i died. I even moved as much as i could to the north to avoid the gopher guards there. But alas.
Pity, i would have liked to blow up the dang gophers' HQ.
