The name itself pulled me in, and the message at the end was a perfect send-off.
You put together a great little project here. I saw you mention that this is your second game, so I'm blown away by how cohesive & enjoyable of a product you managed to get together in a week, outside assets or no.
My only criticisms are exceedingly minor. Firstly, I think you'd benefit from having the jumping bricks stand out from the background a bit more. I found myself getting a little lost a few times when I couldn't clearly see where I needed to be jumping. Second, I think it'd be great if your enemies had a more unified theme, especially if that theme had to do with school in some way. Maybe they're teachers, janitors, the principal, or a bully.
Like I said, small things. Overall I think you did a great job.
Well done! Keep making games!
