Nice puzzle game with a clever level design and interesting puzzles.
It reminded me Chip's Challenge (not sure if this reference is known haha) but with two characters instead!
I like the fact you decided to make us face our other self at the very beginning so we understand who is the other character we're playing because my first reflex has been to shoot myself haha
The music was relaxing and the game made my think hard to succeed but I made it to the end so congratulation for this nice game!
