Hi, this is my understanding about this game:
1. it's a word game and player selects a letter from a 4-letter group to accomplish a word;
2. it contains a badge reward system to display on home screen;
3. it appears words and blanks randomly.
then, this is my questions about this project:
1. is there a difficulty-level system in this game? like word-length, blank-amount, unfamiliar-words?
2. is the animal dynamic or static image?
3. is the whole word blank or show some hint letters of this word?
this is my suggestion about this game:
1. music, audio effect are also important to this game;
2. background image would match the animal at bottom, i mean if it is a tiger, jungle appears;
3. difficulty-level system should be designed carefully, it is the core of this game.
Regards.
