Your cover image serve you badly. The game as a strong aesthetic, with all those particles, and that's not what we image when we see the cover. I finished the game without knowing I can switch to an other dimension using a big exploit. Arrows left/right were not working, so I wasn't focused on the explanations, and the text of the tutorial goes outside of my screen (got a 16/10 not 16/9).
That being said, the controls, the animation, particles, and the mood are great.
(Not sure the balloon are so frightening...)
Well done.
