I think this is brilliant for your first platformer! Just a couple of notes: I thought the clock could jump and it felt weird when it couldn't- I realized we could climb walls. It could definitely be a feature but I would mention it in a How to Play screen or something. The night view is beautiful and the clock almost looks like a full moon, which goes perfectly, but the blocks themselves don't really go with this view. And I found the audio a bit too repetitive. But great work, fine tune it and this will be a very cool game!
