The game gave me a negative initial impression on the first route I finished, but after finishing True Neutral, True Evil and the Final Episode, I really like the game. Certain levels are very lengthy, and there are other levels that were purposefully made incredibly harder. Although controlling Shadow was finicky at first, it was extremely easy to get used to. The boss fights in this game were among the greatest I've played in a Sonic game, and the level design and themes were great as well. The final battle and soundtrack were fantastic. Each run of the game is short, but it was handled well and was an enjoyable experience.

To be honest, I didn't expect anything from this game. The genre was a bit lacking as it was my first SRPG experience. I had experience playing Persona and Shin Megami Tensei, and I knew a few basic mechanics and generally knew what to do. But some battles gave me a hard time. Not to say that the game is difficult, but sometimes you really need to know what to do, how to assemble your team, and so on.

As for the plot, I can only say two words
I've never seen anything like it. The characters are well written, it feels like everything you do in the game has its own response in the characters' responses. I recommend trying it. The music is always on top. RIP Takami Asano.

The only drawback is that the compendium of demons is very small in comparison with other parts.
