In that Game Jam you need to do a game of any type. But you need to follow the rules.

1. The game need to be a spring game, not other seasons.

2. It's need to be a fun game

3. You need to enjoy the process

Criterias are design, gameplay, particles, enjoyment, fun, variety.

Design - this game must be good looking to players can enjoy it more

Gameplay - if in the game is many features and not much (unfunny) bugs

Particles - they can upgrade your game but don't use them too much it will be pure chaos

Enjoyment - if game is'nt to hardcore it will be cooler to play (not for hardcore players)

Fun - the game can have fun story ( or some funny bugs)

Variety - variety of gameplay (or even design) do a game more interesting.

Good luck!
