Nice! a bit too hard for me, I found all 4 keycards but then died to the giant alien.
I liked the platform mechanic and the wall jump.
It was meant to be relatively hard by the way. At least not Ninja Gaiden levels of ball-busting hardness, but you get what I mean
Yeah. The first fast moving aliens looked a bit unfair, but then I realized you can wait them where they change direction, then shoot them with ease.
Hence the "bunch of dumb aliens" part
