Taking care of all your advices, I'm currently working on a new version with Smaller and easier levels.

The time system will be change by one timer by fish to agressivly force people to enter the flow of fishes.

A menu to manage sounds is also on the todo list.

I'm heading an android version, I worked all the recording system to be platform agnostic. I currently facing one issue : the controls currently are not enough good but it goes better each days :)

A new web version will be up in something like 2 days.

I want to thank you again for the great and useful feedbacks you gave me!!
