How does your submission match the theme?
In this game, you must climb an infinite series of platforms while fighting off hungry vultures. Your only tool, a grappling hook, serves as a dual-purpose design, enabling you to both move and attack. Enemies also serve two purposes - they both try to kill you, but they can also be grappled once, helping you to move. You will need to use this skill when you climb past the footholds and face the Vulture Swarm, the second half of the game.

This game also uses concepts from several other GMTK videos. The player is placed into a situation (in the title screen) where they click on an object, and they watch their character grapple up the object. The player now knows exactly how to use the grappling hook without once being explicitly told, just like the video "Half-Life 2's Invisible Tutorial". The game also uses concepts from the video "Mario's Jump (and other Versatile Verbs)". Since the mouse button can do something different if it is held while you are grappling, that same button enables you to temporarily stop reeling in your rope.

Nice start! I included it in my Game Maker Toolkit’s Game Jam compilation video series, if you’d like to take a look. :)


Nice artstyle. The invisible tutorial didn't really help much though, as it seemed that the mouse location could control to some extent the grapple hook, but it was quite difficult to use the grapple hook solely without being able to move around, getting stuck underneath ledges for too many times. At least I made it to the top before the swarm of vultures finished me off. Cool entry!


I dig the aesthetic. And good point about the Invisible tutorial thing.


Very nice game with great music.  Reminiscent of 80s video games!
