This bundle contains 4 games of the Blackwell series, made by Wadjet Eye Games, redeemers of the 2D point & click genre. The story follows Rosangela, a common girl, who discovers that she is a medium, and can talk to ghosts. Her companion, Joey is a ghost too, and you can control them both to help lost spirits find their way into the light, and solve other misteries.
The story is interesting, the characters are likeable, the voice acting is good, and - thankfully - the game avoids the common problem of point & click games: hoarding junk to combine them in twisted ways, to figure out a puzzle. The puzzles here are clues, what you can combine to get more info, but usually you only have to talk to other characters to progress, and your inverntory has only a few items.
In the first game (Legacy) the graphics is quite basic, and I encountered quite a few bugs for this kind of game (most of them in conversations, where the voice didn't match the text). Every game in the series is an improvement from the last game regarding the graphics, the interface, the menu, the conversations, the puzzles etc. So I'd give Legacy 3,5/5, Unbound 4.0/5, Convergence 4.5/5, and Deception 4.5/5.
All episodes can be finished under 2-3 hours, so this bundle is a good buy. And there is Epiphany...
