A typical rail shooter.

(Technically snap judgement, couldn't beat the final boss)
While in some part i feel it's easier than the NES game due to not having to awkwardly dodge enemy fire, it still falls into the trap of lots of enemies coming in at once and always getting hit. Sometimes there aren't even many health packs to find so that's a real blow.
So yeah, game is hard and not very fun, what a surprise.
