I just woke up and this proved to be a good brain exercise. sound would have added a whole new dimension for the game, something relaxing and interactive.
does it increase in difficulty, in this prototype? I love that you have multiple parameters to control difficulty with from the
1- size of the grid, 3*3 , 4*4
2- speed of reaction
3- wouldn't it be more engaging if the leading light wasn't only coming from the left grid but also from both? that would be awesome
good job man :)
