Oh MAN I love the black and white art for this. I think it pairs especially well with the concept. Visually striking and also fun to play with!
Like a few others, I felt the timer was a little short in the beginning levels - but on the third level is when i first noticed it, because its also white/black and that was a much shorter amount of time for a bigger level. I think making the timer some other color and adding a little vibration to it as time whittled down to make it more prominent and easy to notice could be something to consider.
This was a really cool and fun entry, awesome work! :)
If you have time, I'd love to hear what you think of our entry:
