Tigsy and the Stars
Even the addition of a few different coloured stars you need to avoid or grab in a certain order doesn't make this game particularly challenging. While it could do with a bit more variety, the soft visuals, sleepy music, and simple gameplay ultimately puts me in mind of an Orisinal game. It's accessible to pretty much anyone, and is about perfect if you're looking for something easy and relaxing. This time, collecting achievements also does more than massage your ego; for each one you earn, you get a small boost to Tigsy's abilities. It's a little touch, but a clever idea; earn your advancement through good ol' fashioned skill rather than just, say, leveling up or getting a high score. Of course, if you don't have any of that good ol' fashioned skill, you're out of luck.
Fortunately, even the less, ahem, "skillz" inclined of us will be able to finish Tigsy. Even with thirty levels, the game is pretty short. (To give you an idea of how short, one of the achievements is actually granted for finishing the game in under eight minutes.) While some may find the gameplay too simple or slow, Tigsy and the Stars is a day-dreamy little arcade exercise to cap off your day, or to limber up when you're supposed to be working, BOB.
... I... I don't actually know any Bobs who would be at work right now. I was just hoping to freak someone out.
