The overall atmosphere is cute but a little fragile and beautiful, which I really like. I especially love the animation atmosphere at the opening, when clearing the stage, and when the player is hit! The mystery of why the cat is running away with the treasure has not been revealed since this is still a demo version, but I'm looking forward to seeing how the story develops in the future.
To be honest, I felt the difficulty level of the game was very high, but thanks to the atmosphere of the game combined with the music, the time spent struggling with the game was not painful, so I enjoyed it.
The Japanese translation was good overall, but the proper noun "Nova" should be "ノヴァ" instead of "ノブァ". It would be cuter!
