The Unique Adventure is exactly as the title suggests, it's very unique!
The game is driven heavily by a narrative experience so if you aren't a fan of those types of games, than this isn't for you. If you are, then you will love it!
The graphics and environment look very nice for an indie game as Darkest Desire Studio kills it again in this department. The interactions and controls all handle extremely well as I never found myself straining to open a door or interact with an object. The music and soundtrack are all perfectly spot-on and match the tone of the game. Even the voice acting makes for a few laughs and just adds to the overall atmosphere.
There are very few negatives that I could find with this demo: maybe that it was a bit too long for a demo with some parts making time drag a bit? I don't really know, that might be grasping at straws at that point.
Overall, The Unique Adventure is a REALLY fun experience and it certainly sets a unique bar that other games should seek to reach too, great job again Desire!
I made a Let's Play of Unique Adventure so I hope you check it out and let me know what you think!
