Took some time to play the demos of Cloning Clyde and Ancients of Ooga. They are both puzzle platformers from the same dev, sporting similar mechanics with Ooga being an evolution of Clyde.
In Cloning Clyde the basic premise is the titular and not too bright character has been taken to a research lab for experiments which promptly go awry. He ends up being cloned many times and, not being too cool with that, tries to escape. Besides basic object manipulation, the cloning mechanics are the tools with which to solve puzzles, e.g. by using a number of clones to keep pressed many buttons at once so a certain gate will open, or by fusing a Clyde with an animal to gain special powers. Think Brundle Fly but without the scary parts. So you can fuse with a chicken and fly to reach platforms you wouldn’t be able to otherwise, or with a barrel and gain the ability to blow up walls etc. The game is basically a sequence of more or less disconnected levels where you have to destroy a certain numbers of “security machines” before you can head to the exit, and there are bonuses for gathering collectibles and being quick.
Ancients of Ooga has you are a “spirit” which can possess selected members of the tribe of Ooga, in order to free them from the tyranny of the Booli. The Ooga-ni are some sort of furry, colorful antropomorphic critter. As I said, Ooga is like a bigger, better, more polished version of Clyde: it’s 2.5D instead of 2D, has better, larger graphics, offers more options for combat, lets you use many types of Oogas with different powers, a more advanced inventory system (while in Clyde you can only pick up things and then throw or drop em, in Ooga you can store things in your belly), has a more elaborated story with plenty of original and well-made cutscenes. The expansion of the basic formula works well, although sometimes this has the side-effect of making things more complicated and confusing.
Both are cartoonish and humorous in style, definitely aimed at a younger audience. Clyde has a more basic look which I didn’t really find that pleasant, but the gameplay looked solid and inventive.
There are some problems with their Xbox360 heritage. Namely, to change the resolution and go fullscreen you have to edit a text file. I didn’t bother to hook up a gamepad and played with keyboard, works fine as long as it doesn’t bother you to use arrows to move instead of WASD. Also, while Ooga has pretty large characters, in Clyde everything is smaller, and at least on my old 19" panel looks a bit cramped, like it was designed with TVs in mind (also both are seemingly locked to a 16:9 aspect ratio which reinforces this impression).
As far as puzzle platformers go, they haven’t the flair of Trine or Vessel, so if you’re unsure about getting this bundle, my recommendation would be to try the demos on Steam.
