Welcome, welcome.
We are 3 game developers creating Sammy the Snowball for our minor Game design and development.
Our current assignment is to create a 2d android game. We went through alot of ideas, one of our ideas was to create a game revolving around growing bigger and smaller. This idea was later developed into that of a snowball rolling down the hill gathering snow.
After a lot of discussions about mechanics we realised that the discussion will never end. But nonetheless we started developing our game. In just two and a half weeks we managed to create the current version of Sammy the Snowball!
Even though it is far from done I encourage you to play the game and share your thoughts.
