I may have played casual games here for a year now, but I can't rightly judge what is easy or hard for other gamers, so here are my bare-bones for why I loved this game (playing on the easiest setting).
The beautiful song on the title screen with the VW transporter (full song at that - if you watch the credits you get a link to the singer's website) really sets the tone for the beautifully weird feeling of the whole game, from the graphics to the music to the gameplay (creating those symbols with cards and shooting targets to turn various gears into the correct position I have not seen used before).
The voice overs are lovely. It all sounded British enough for me, but I'm not a native Brit. The cutscenes have this weird - part photographic part drawn appearance that works really well - especially in the flashback scene to the youth of the heroine). And the places and things you interact with ... they remind me of ... I don't know... graphic artist Möbius' sense of the weird?
The HOD part is fairly average, but the scenes that the HOD are set in can be fun.
The game alone - the SE ending - is fully sufficient and happy end enough for this slightly melancholic story, but the bonus game gives you more of a sense of completion because the heroine deals with the original curse and its caster in a fitting way (wait for the amazing drawgate guardians).
Kudos to the graphic artists and designers here, and the sound engineers who mixed up into an amazing brew. I'd buy another game in this vein right away.
