I'm struggling with the game. One level jump was taken away. Can't find a way to get it back. I restart from the beginning, and on the same level A stopped working. I couldn't find any way through the level in both instances.
I really liked the jumping.
I do think I jumped over an enemy in front of the box that gives A back. But there was no way to get back to the box.
I was just confused about your game but the more I think about your game the more I like it. I didn't like the execution of your game. 4 stars. Keep Growing.
