Woo, just finished my 100th game this year, Journey of a Roach :o
And can you recommend it? (I'm still wondering whether I should get the Humble Bundle or not, and this is the only game I'm interested in, apart from the German versions of TWW and Chains of Satinav.)
Well, overall, I enjoyed it. It depends on how fond of Amanita-style games you are - there's no dialogue, only weird sounds; it's very cutesy; and things are communicated via images in speech bubbles.
The game is fairly short - although, it depends on how fast you breeze through the puzzles (I found only one of them to be particularly frustrating). The game has an achievement for finishing the game in under 18 mins, so that should give you an idea of the amount of content in the game.
Your character also has the ability to climb on walls, which causes the camera angle to rotate with you. That was something I personally found incredibly nauseating - keep that in mind if you think that would also make you feel sick. Also, there are some areas that seem like you can walk on them, but you arbitrarily can't. So, the movement in the game can be a bit awkward.
Basically, it's pretty enjoyable, but I wouldn't strongly recommend it. Perhaps it's better to wait for an even cheaper price.
