It was a real bullethell experinence!
The movement of the player and the enemys are fluid, but when enemys are floating, it is a bit hard to dodge.
It would be better with some story, but I understand that, the story is not so important for the kids... But some cutscenes with the best ninjas, or together... like a TMNT movies.
It was an exceptionally fun and cute game.
Good work!
