the problem with higher speed is that there is a higher level of precision required and that would not allow for harder puzzles, although if i went off screen with the level that might have been possible...
the sound on the other hand i forgot to encode it... =))
i am a bit surprised that you died though... maybe you were not patient enough? (the action system was a interesting idea that fit better in this kind of platformer than a lives system, and i was initially thinking of having a number of actions dependent on the level, but i did not have time to play test it so i just gave a number of actions that i considered to be at least more than enough... given that you can select any action at any time)
