Hi
about genre:
I have played few times the puzzle genre. It likes me enough.
about your opera:
the presence of a structured organization of the game has its good impact:
the menu at starting that lets you do different actions, the presence of different actions avaiable, an advanced use of sprites with the tecnique of more layers, the sound and music, the three characters with their personal powers, the support of different input devices, the help of actions on the top of window.
Suggestions:
1. it is possible implementing also the mouse as input device
2. it can be useful to have improve the help with some helpscreen to introduct the story of the game and to have more informations about each character of the party and/or about the final goal of the game or of the level to end.
