The concept of only having one turn to finish the fight was neat. However I didn't really like how I have no idea what the enemy's abilities actually did. I felt that some of the enemy types were sort of trial and error and given the only 1 turn to figure it out I ended up just straight up dying. Overall the concept was cool but I felt the game was a bit repetitive from all the retries.
As a side note you should include some controls on the game page because I wasn't actually sure which button would back me out of a menu.
