Loved the idea and overall the game and its puzzle nature are a lot of fun! The puzzle design is also surprisingly good for only really having 3 different types of characters in 3, 1 and the evens! I think my only suggestions would be to also allow the 'Up Arrow' Key and/or 'Space jump and make the double jump 3 character a little more floaty as there were a couple jumps I needed to use the arrow keys for in moving the character to allow myself to be able to both jump and press a button or switch characters whilst in the air. Though overall I really enjoyed it!
