It’ll probably take longer to read this post than it took me to complete the game. One Strike is a one-on-one fighting game with the sort of graphics early Game Boy Advance games had, with colour palettes to suit the very dark GBA screen. Games like Castlevania: Circle of the Moon looked hideous when blown up on a big TV via an emulator, and so does One Strike.
As the name suggests, you need to strike your opponent just once to kill them. It’s basically one-hit-kill Samurai Shodown.
And, with only about 8 opponents, it doesn’t take long to simply press dash-dash-attack your way through them all.
I’m glad the game was free because I’d certainly never pay money for something this shallow, short, and offensive to my eyes. Perhaps in two player mode there’s more strategy, but I won’t be playing it again to find out.
