Thanks! Actually there was a fleeting idea about make him holding a phone while popping the bubbles, but didn't connect it with the bubble wrap '^^. Altough, there was another idea too for that based in animating the siluro hands making the effect that we is unrolling the bubble wrap but we didn't make it in time jaja.
We have also planned to add the extra difficulty but we were at the final stretch so we decided to polished everything instead of adding new untested things (for example, the probability of having already popped bubbles was added at the end).
Thanks again and do not forget to post a screenshot with your best result!
