I really like the idea of switching between mad and sane worlds to go forward. It was cool that sometimes you were forced to take the green pills. If you spend more time fine tuning the levels I'm sure you can make a full fledged game out of this.
A few notes:
1- In games like this use raw inputs, soft movements really mess with what the player plans to do.
2- If you had time, I suggest designing levels that can be passed with both mad or sane choices, each one with its own pros and cons.
nice game. Good job!
