Also usable for game logics, but it is heavily depends on Scene2D, it means that it is not %100 MVC supportive. However for games like puzzles, brain teasers, low-level platformers, low-level defence games, other low-level causal games, it may be suitable. Again, I warn you, it is not %100 MVC supportive.
