Neat graphics, but I don't feel any strong attraction to this game whatsoever. The first time I died it was near the entrance to the region so I repawned right there and didn't care too much. However in that same room I saw the exit and was about to move on when I died, and I didn't bother trying again. I know it's because I'm a lazy bum, but I'm a lazy bum who felt like there was nothing to gain from going through something twice.
Ideas for improvement? Well, the music was a nice loop, it didn't annoy me, so good job there. The camera seemed a bit buggy when scrolling, I don't know how to fix that, but it did kind of seem to give the game a unique feel, so passable job. Motivation? Perhaps a better 'story,' some mechanic that makes you feel like if you progress it will be less likely that you're going to die. I enjoyed it when I got the sword, because I could fight enemies and progress. But that enthusiasm was quickly put down when I had to time passing those arrows.
In the end, I think it's the arrow that ruined it for me. It was just sit and wait, and you MIGHT not get hit. Maybe just don't have as many of them? And yes, I know this review was perhaps too long, so please accept my apologies.
