This has a neat concept and these levels do a good job at introducing the main mechanics of the game. This has a lot of potential if you implement some more interesting level designs. That said, it could be frustrating to get the arrow  to shoot where you wanted it to, especially if the level was mostly flat. Some of the places where you needed to aim to move forward felt unintuitive and imprecise. Solid start, just needs some polish.

One thing that I think makes this game more interesting to play is that where you point the aim reticule isn't always where the hook lands if something blocks the way.  It became a sort of a-ha moment on one of the last few levels where you're at the very bottom of the screen and aiming close to you doesn't really get much distance, but aiming way far away actually lets you move to where you wanted to aim.

Really cool little game.
