It's a port so don't expect freedom and like in other games, cutscenes are on a flat screen. Graphics are decent, gameplay is smooth but I sometimes, towards the end, I experienced lag for some reason. No skill is required, you have the lazer and you just unload your bullets till the enemy dies no matter if you are just hitting the head multiple times. Bullets are easy to have and no clue how to check the hp. If hit, you just have to wait a little bit. You get to have 3 weapons but the primary, that you cannot change is not really useful in the end as enemies are harder. I had a blast and I wished there was a final boss but it's like the original game. I recommend it but not for the whole price unless there's a multiplayer option as that would be a game changer.
