Thank you very much for the words, they really mean a lot!
I have received various comments regarding the jump as an issue, but it was intended to be (obviously with a little more polish) the way it is. We wanted the player to jump a fixed amount of tiles and in one direction, aiming to more conscious puzzles and a simple movement, but maybe it wasn't the right decision in the first place.
Do you think that with more levels and a better tutorial the jumping would seem more familiar and the impression more positive? Or maybe the right path to take is to have a more common jump control?
