Ok, so all I get is a blank white screen, no matter what I do. Is this already part of "figuring out the game machanics"?

before i can reselect earlier levels to replay nice game but i can not see on what level i am now at could atleast put some numbering in it

First of all glad we have a linux build. After finishing the game and earning the first achievement I could see in witch levels I didn't have a star so I could play them again and earn the second achievement. Could do esc and move with those arrows on the screen and I could choose to play a non star level by clicking enter. I quit the game somewhere on the ending and when I launched it again to finish the last 2-3 I didn't have a star there was no way of seeing all the levels and instead I was playing rand...

I would like to play this game on GNU/Linux. Seeing as the Unity engine supports easily making Linux builds of games from any supported OS, I suggest that the developer should just publish such a build; they almost always just work, and if not, we'll let you know....

Help with fewest moves for level 25? I've tried and tried but just can't seem to figure out the trick...
