Really cool idea and nice graphics. Very hard game but I did manage to win in the end! One bug I noticed, I think if you're pressing down one of the movement keys whilst you swap deer, the deer that you swapped from doesn't begin to get stamina back. This is frustrating as you have to make sure to take your finger off the walk key just before you swap each time. Other than that it's a good game well done, you should keep working on it :)
