Pretty fun Ninja Gaiden-like, if you enjoy NES style action platforming you'll probably enjoy this. It stays pretty true to the games it's based on while making the controls feel just a tiny bit more modern and adding some interesting twists like purchasable temporary upgrades at checkpoints. The story is pretty bad, though I don't think it's meant to be taken seriously and it definitely gives off the Ninja Gaiden/Mega Man vibes it's going for. The latter third of the game is quite the difficulty spike, I still enjoyed it but the checkpoints were very inconsistent there, being too easy at times and brutally long/hard at others. The final boss was quite the challenge too, but in a very enjoyable way. I think you probably already know if you like this type of game, but if you do it's a solid one of these.
