Going back to the beginning after receiving an arrow hit was unforgiving.. haha I like the idea, but the camera could have been a little higher, mostly because of some depth perception issues. The shadow of the character helps in letting the player know where he’s going to land, but, because of the camera, when the player jumped too high (Like when using the springs, for example), the shadow wasn’t visible at all until the very last moment, when it just wasn’t helpful. Some minor tweaks of the camera here and there (Welcome to 3D games! :D) will provide a better experience overall.
That’s not to say that I didn’t like your game. It was fun, just way too hard when it didn’t need to be.
