The search for the answer to life, the universe, and everything can lead people to do some pretty strange things. For example, you could try building a time machine (disguised as a grandfather clock, because police phone boxes are so cliche) and jump straight to the start of time itself. That's the theory, anyway, in Adam, a short puzzle platformer created in 48 hours where your own worst enemy is yourself!
In order to generate enough power to make the great leap back in time, you need to gather heat from the yellow heat zones scattered across each level. Grab your grandfather clock with [Z], walk over to the heat zone with the [arrow] keys, then absorb the heat by using the [spacebar]. Be careful though, because every time you make a collection, time rewinds itself, and an extra "you" is added to the universe, following your exact moves! If you run into a previous version of yourself (running into a previous clock is safe), time is completely reset, and you have to start collecting heat all over again.
While only a few levels long, Adam gives a solid challenge that require a bit of planning and perhaps patience. Since the key to the puzzle is avoiding collisions with yourself on a mostly-flat landscape, you'll need to develop a system for pausing at the moments and ducking into corners; don't forget to use the clock in the corner as a guide! The final level does involve performing a medium-level trick-jump several times in order to proceed, but otherwise the game lets the platforming stay out of the way of the puzzle you create for yourself. Time's a-wasting, and who knows if you'll be able to get it back or not, so grab your clock and go!
