The idea of the game is super cool and the premise has the potential to make the gameplay super interesting. The overly simplified aesthetic of the game and the background music create that atmosphere of loneliness.
Great work overall, but there are a few things I didn't like.
The controls. They just feel too clumsy. The roll isn't responsive enough and I didn't feel like it was doing something.
And there is not enough feedback for the player. I feel like you should notify the player in some way that what they are doing is either good or bad.
While playing you always know that you are going to die at some point and I felt that my skill or my interaction with the game wont play a significant role in keeping the player alive.
Hope the feedback will help you for your future projects. Keep up the good work and keep learning. Have fun developing!
