Great game, I love the art especially. It looks very simple and well fitting for the game. Music is also nice and wasn't too repetitive or annoying (nice choice on that).
It also felt like playing where is waldo when you get clues of what Ivan may look like. Bonus points for also making every game feel different, i was going to cheese it the second time around and talk to the same person on the event area where I found Ivan but i was pleasantly surprised when it wasn't him.
Only difficult bit was when characters are too close to the edge and when you click on them, it takes you to the next area instead of talking to them.
