Simple art, smooth animation, fast development but closing the story, excellent atmosphere. It's amazing what can be achieved in a simple idea but with an entertaining story development. This game has great potential, I imagined that after using the gym, the blue cube would become so big that it would break everything in its path, or that when it gets home, it would go to sleep and that would give it the ability to jump even higher and go over a large part of the map. But, despite that, it is not all that it promises.
Congratulations on creating your second game jam and developing this fast and fun story!
Keep up the good work!
