Oh, thank you very very much for your complete feedback ^^
About the walljump, there´s indeed a safe zone to practice… The begining of each level has a huge wall on the left part of the screen with a generous platform :P. You can practice there all you want (well, until drain all power, of course, hehe).
And I have to admit that you’re very observant, and you’ve seen through me… Indeed, I have a weakness for including lyrical or poetic messages in video games in one way or another. Not always, but when there´s a possibility ^^! I really appreciate your words about that :)
