Really cool hidden gem from later on in the NES's lifespan. Power Blade has some cool level design where you take more of an exploratory approach as opposed to more traditional progression. In 1992 this was still relatively uncommon, and I feel this does it quite well given your mobility options are limited to running and jumping. It can lead to you missing a crucial key to get into the boss room, so I probably would have preferred seeing them make the levels a bit more complex while removing the keycode need. As mentioned, movement is limited and your upgrade path is basically just increased range and power armor to help tank a few shots and get a larger spread for your weapon. In hindsight. You lose this progress upon death and it feels pretty unsatisfying to play without the upgrades, so there are some pretty critical flaws (Unless you use save states to keep all your shit, which I definitely did). Perhaps the game was only fun because I removed those design barriers? It doesn't really matter because this is MY REVIEW. And my review says Power Blade is pretty cool. 4/6
