Nice work! Would have loved to see the sleep theme pushed a little more, but the game plays solidly and has a nice clear look to it. Feedback wise, one thing I'd caution with making a platformer like this is creating situations that can kill the player before the screen catches up, which will often lead to deaths feeling unfair (Specifically the part where you fall while being chased by spikes aha. Skill issue on my part maybe?).
Even if you didn't get the ending in, getting the game out there on time is a great achievement - good work!
