Hello, I'll address your points in topics to make it clearer.
- Will the main character have any unique doujutsu - Well, the main character will unlock a doujutsu in this game. However, I can't say more than that to avoid spoilers.
- Will the main character be able to create his own jutsus? - Yes, he will! Some jutsus will be introduced during the game's storyline, while others will be possible through a system we plan to add in the future for jutsu creation. However, this system won't be implemented in this particular game. We envision each game to represent a different 'era' – for instance, one game set in the 'classic era', another in the 'shippuden era'. The current game is set in the 'Academy era', and it doesn't make sense for a child (the main character) to be able to create jutsus on his own.
- Jutsu combination - It's likely possible with the system that allows jutsu creation. You could create a jutsu that use 2 or 3 elements, for example.
- Customization - We plan to introduce character customization, specifically regarding clothing and accessories, and this will be implemented. Our main concern is integrating this customization with the CGs. We are planning to incorporate several CGs, but with the added customization, we might need to depict the main character in these CGs wearing their "default" clothes. However, you will be able to wear items like Kakashi's mask and position the headband in various places.
- Game in Boruto era - We currently don't have any plans to create a game set in the Boruto era. We are projecting between 4 to 6 games for this storyline. Given that our team is quite small and our ambitions are large, it will likely take years to complete all the games we've planned. After that, we might consider a game set in the Boruto era.
