Thank you for your feedback! We’re really glad that so many of you have noticed our efforts regarding the graphics. Fall damage will definitely be implemented, as it conveys the sense of physics in the game, which we’ve been working on for a long time. As for falling off-screen, we’ve already considered that in the future, this won’t mean the end of the game. Wall-jumping has been simplified as much as possible, with an eye toward later stages of the game. And as you correctly pointed out, the game really needs tutorials, which have already been partially created but not yet added to the game.
Unfortunately, right now we have to work on mechanics to simplify the game instead of working on adding new features. But one way or another, in the upcoming versions we’ll add enough to simplify the game and enough to introduce new gameplay.
