A single screen of platforms, a main character, some collectibles... you heard this a million times by now I assume? I won't argue, it's sounds boring already! What made this game stand out from the rest for me is that the levels are quite simple (at least to begin with!) so you pick it up and play in seconds, and you're constantly in time attack mode, which means you have to keep moving, no time for thinking ahead of strategies, just charge blindly!
There are two other items, one resets the clock (the time you have is common for all levels) and the other is a switch that opens/closes doors etc.
For a 5-minute break it's simply an amazing game! (well, you start it as a 5-minute break, but then it sucks you in as you want more and more :)).
