here's a tip
Your going in a good direction with this just add some christmas music in maybe even a sound effect when u hit a snow flake. And have it set so that if a snowflake touches the bottom u lose. Play with the idea and change it as you please. Just keep in mind that what keeps people in a game is the ability to defy failure. Have a way for someone to lose. Keep a point system. Make levels where more snowflakes fall each level. This is just a good idea just not finished yet. YOU CAN DO IT!!!
