Mouse. Great take on a classic concept
A mouse avoiding game with... wait, no, it can't be... some semblance of a theme? Much less a plot? Scandalous, absolutely scandalous. we can't have that here.
The level design, visually an mechanically, was very well done. The music fit each level as well, which is a big plus (not just some random too-fast techno tune from the audio portal like most of the games here... pick something appropriate people!). I'm normally much more long-winded in these responses but there's not a whole lot to say... looks good, fun and challenging to play, a solid variation on a well-tested theme.
To everyone: try this kind of game with a tablet sometime. it's interesting to see where one fails with a tablet as opposed to a mouse, although this may just be me (I rarely use a mouse anymore, and when I do I have the sensitivity way low so I often don't move fast enough... with a tablet and absolute positioning on such a small window, moving too fast is a more common problem).
