Im actually surprised that you made a video from our "game"
I want to thanks you for give it a try, since this is a project more than a game itself.
The problem with that is that we didnt even specified the controls from the game.
In this game you are able to stop time by pressing "Q". Looks like you already discovered the character movement (With A/D and Space)
When you press Q the water (in that case) stops, so you can jump at them and go to the next area.
For anything more, feel free to reply!
