Hey man I really appreciate you trying out my game, it means a lot. I'm curious what the specs were for the pc you were running the game in. The grappling is actually instant and is based on a short cooldown timer that appears over the players head. When testing the game I ran it on just my computer and laptop which might have more processing power than some other devices. It didn't seem to be running well at all on your computer which might be where a lot of the issues came from. That being said, the game definitely is not without it's issues lol so I appreciate all the feedback, thanks for trying it out :)
