This was an interesting concept, with movement that makes a while to get used to. I agree with some of the comments below that having an easier tutorial-esque beginning would have been nice.

Very fun game, but i would like if first levels would be easier. I took a long time for me to realize that i can zoom in and out with scroll wheel.

As soon as this started I was like "Oh boy", but I actually got used to the handling. I like the freedom and level selection. Good job! Needs music!

Very nice movement system! It is quite difficult at first, but when you get the hang of it, it's super fun to fling yourself through the levels. I found the difficulty curve quite wonky, after level 3 or 4 I think the levels started getting simpler. I think that just moving around the order of the levels might fix it.

I appreciate being able to set the camera to be static, you can't really see much with the camera following the player. I think that this should probably be the default setting.
