I liked the visual cohesiveness of the game and trying to get to all the balloons before the bears get you. :) It was nice to have the playful music in the background and the satisfying "pop" whenever I reached a balloon.
I wasn't quite sure how the "Strength through Weakness" theme played out in this, though. If it was there, perhaps there's a way to make it shine out a bit more. (Edit: I missed the "View game page" link at the top, so I see now that the "Strength through Weakness" theme was through the type of player character rather than through game mechanics. :) ) Also, I wonder if having the bears be invincible would help drive the player to focus on the task of popping balloons by having an ever-present danger. During my first playthrough I just kept running with the bears on my tail, but then I realized on my second playthrough, to see what happens when I die, that you could actually defeat the bears by stomping on them twice; this meant I could clear out the building of bears and then take my time getting to all of the balloons, which wasn't as much fun as running for my life. :D
