For anyone confused, press space to start.
Also, I don't know why, but it doesn't react to the trackpad, and instead only reacts when I use the touch screen. No idea if it's just a side effect of not having a mouse, having a touch screen, or something in the programming.
Aside from that, these types of puzzles are great, and I really enjoy this game
the game doesn't start.
good game but needs elements to keep you playing
I can't even get past the starting screen, what are the controls?
It feels like sudoku!
