It was ok. The biggest flaw is the lack of a map. An in-game map would make this game so much better.
For a gameboy title, it's very impressive. It controls well enough, the level design is pretty good, enemies are just okay. Music is atmospheric when it's there. Good for the hardware.
I played the colorization which looks really good.
I definitely recommend playing this one with a map. I just can't stand wondering around not knowing where to go.
Camera can be a bit too close, but it seems like the game usually takes it into account, you're not really making blind jumps.
