Almost all the basic mechanics are in: basic platformer physics, bow aiming mode, arrow physics, level win condition, and automatic level switching.

The last mechanics element I wanted to implement are springs, which will propel both the player and the arrows vertically or horizontally. Once that's done I can start adding puzzle elements to the levels (the idea is for the player to figure out the proper combination of spring jumps and arrow rebounds needed to hit the bullseye).
