"There was a bug introduced by an update of the game engine (to fix some corner cases) which prevented some songs to load, that’s why many of you got stuck on loading screens. The bug is now corrected and everything should work normally." ------------- I can't imagine what one has to do with the other, but I'm still stuck on the loading screen (chrome)
As far as the resolution issues: It's okay to charge a few bucks for a nice hi-res version (but not with the pitiful English included), but it's not okay to not respect browser zoom. There's no reason that the only way for me to double the size of the game (without improving the graphics quality, mind you) is to actually change my monitor's resolution.
Pretty good overall, but it could use a little polish. It would be nice to see an individual net highlighted at a time -- it's sort of a pain to try to trace out which squares belong to which nets on the higher levels.
Also, as some other people have pointed out, adding in some other polyhedra could be quite interesting (and challenging).
And finally, a level select/skip option would be nice, as would having a little popup to let you select which number you want to fill in, rather than having to click-cycle through.
Oh, and just a couple not-so-important things. An option to change to view the nets with pips instead of numbers would be cool, as would an animation at the end of each level showing the nets separating and folding up into cubes (but I gather that would be tricky).
