super good game, feels very nice to play. the grappling hook felt a little strange since it didn't really pull me up but it was good for the extra jump. directional dash was super fun to cut corners with. great work!
In regards to the grappling hook, this is a bug. It happened to me once during submission hour, but never before or after, so I don't know what causes it. Restarting the game solved it for me.
