As someone who hates visual novels but played this one just because I love Sonic: it's cute, it really is, this game's greatest quality is seeing the characters interact, Sonic Frontiers already presented some really good character writing and this game just continues the trend.
The story itself is nothing crazy and I thought it stretched itself a bit too long by the ending, but as I said, it's a cute, fun experience. Don't know if i'll ever replay it tho, I really don't like this style of game.
