I beat it by 30 minutes of trying! The first time a didn't understand anything, but I was trying again and again and I did it. I was a little bit comfused with final puzzle. But I guess puzzeles should be like that, you need to try, you need to think. Really interesting mechanics, your game impressed me. More time to do more stuff.
Gameplay is cool, but a little bit clumsy sometimes.
Graphics minimalistic and nice. White and yellow colors have a good mutch.
There is no music and sound(only one which surprized me, xD), so this is a big minus. Music and sound in 99 percents makes 60%+ of gamefeel in my opinion.
So, i like it. Really good job.
