This game is very fun and easily enjoyable. It's simple, it's appealing to play, it provides challenge but player controls the difficuly themselves by choosing to combine movement and go fast or not. It also looks very nice, simple but solid style. Minor issue is how physics and gameplay is not polished enough. In a game like this, you really need to add sound (and maybe visual) ques to express movement in an intuitive way, sound of jump, landing, screen effect to express speed, everything that helps a player feel where they are and where they go at every moment. And man, you NEED air control. Good job, I hope you continue to improve and develop awesome games!
