This game was very well done, from animation to controls, to audio and story. Of course there's the ever present issue of not having a save option, but this just adds on a layer of difficulty to the game, forcing you to make sure you don't screw up, and giving it a classic feel. Another issue is that unless you check your inventory, you haven't any idea how close to death you really are. Avoiding the health bar design may be personal preference but I'd like to see some sort of reference to how injured you are.
I quite enjoyed the puzzle aspect, mixed in with a varying top-down and side-scrolling shooter. This game definitely has a lot of potential and it's by no means wasting it, even if it could be tweaked slightly here and there.
Looking forward to updates and more.
