Oh..really sorry about that!
Player 1 has A and S keys for movement and W for jump and double jump.
Player 2 has left and right arrows for movement and up arrow for jump,there will be circular grappling points like this shown below.Player 2 can grapple hook by pointing the mouse in those grappling points,click and holding.
we were not able to implement the tutorial screen at the last time and we are sorry for that because it made the entire game more confusing for a lot of people.
Hope u will try our game again!!
