I decided to create a new design as my previous design (see Level Design - Old Sketches) would be too time consuming and make the level too long so i settled for a short level that still includes many of my original ideas for the level, including my one way valve, platform idea, and a new addition of a locked door with a coin behind if the player finds a key to unlock the room
I also added a storage area for the key to be found in, if the player is feeling adventurous as well as added another platform sequeence
I created this design on a sketchbook app
