Asterium

I love the basic premise--it's a nice little logic puzzle and there's a real satisfaction in revealing the picture.  (I'd recommend not titling the levels; I didn't notice them at first and tried not to look once I knew they were there.)

The presentation could be a little difficult though.  It was sometimes hard to see the removed lines, which made it harder to use information like "(non)consecutive)".  It could also be hard to tell which lines were borders of regions--specifically, when mousing over a number in a region, the color change made it clear which possible lines were borders, but not always which already-set lines were.  More than once I moused over a 3, saw three possible lines, and started clicking them without having noticed that there was also an already-clicked line that also bordered it.

But as prototypes go, it's quite nice!
