This game is the main content of Sonic-Alpha, and to some extent did what the producer wanted to express in terms of numerous fighters and war direction.
The downside is that there is still no save and load functionality, and the story and mission are poorly explained in the game.
However, the following changes were made in the one-year update:
In its first release, it was just a nine-level arcade game. The language was English only.
There are now 16 levels of main game, 3 levels of DLC, 4 levels of DLC fighting game, DLC puzzle games, 14 tracks of free music and a PDF manual. It now supports 20 languages.

Thanks to the all players who invested in this game in the first release.
