Having spent a chunk of my youth in Quake II mastering strafe-jumping and practising tricks and routes on maps until I could do them backwards, I’m up for a time trial first-person platformer. That’s the idea of Seum: Speedrunners from Hell [official site], which launched today. It’s a string of short zippy levels with platforms to leap between, buzzsaws to dodge, walls to blast, and secrets to find. It’s got a demo too so you can try it yourself. I had a quick bash myself.
