About this game
Ser Jorryn is a precision platformer built around the simplicity of classic arcade gameplay—what you see is what you get. No upgrades, no hidden tricks. Running and jumping are your only weapons, backed by modern responsive controls because not all things were better in the ’80s.
Navigate tight corridors, moving and crumbling platforms, spike traps, and all the elements that shaped platformers in the heydays of arcade. Quick deaths, instant respawns, and focused levels keep the arcade loop alive: run, jump, die horribly, repeat.
You play as Ser Jorryn, a knight stripped of his weapons and locked in a cursed dungeon by his drunken uncle, who bribed a witch to fill the place with horrors. Escape the depths and exact the ultimate vengeance—claim the right to betroth your niece, as was the custom at the time.
Features
• Arcade-inspired, skill-first platforming.
• Tight, modern controls.
• Handcrafted levels which will gradually test your skills.
• Knockback-based enemies that turn mistakes into chaos.
• No weapons—just movement, jumping, and timing.
• Instant respawns for fast, repeatable challenges.
