Construct 2, good choice!
I'm sure you're aware already, but some of the transitions were a little buggy (zooming in the wrong places) and the transitions were a little too slow for my taste (I'm impatient, I want to get back to the game!). Would also be nice if the player controls were locked until the transition finished, there were a few times I dropped my balloon before I could even see where the people were. :)
