This game feels impossible to complete for me for the reason that this game seems to not have the delta-time to multiply the physics steps update.
Since there is no fixed fps then some user may find this game runs at a different speed on devices. And also could be impossible for those who has high framerates, not only the game runs smoother, the game-time also becomes faster which average people wouldn't have much reaction time for that.
There is also random crashes sometimes during the gameplay.
Not to mention those issues, arts in level selection section looks good. Art style in this game is the most I admire in this game. Others I honestly don't find much good about them.
