Fun! I love punishing side scrolling platformers. I found myself fighting the controls a little, like when jumping off the end of a block I like a little more forgiveness for jumping after hanging over the edge, but I got used to it. The music was fun and I liked how it kept changing.

That last level is really frustrating. The whole game spikes in difficulty a little too quickly, I think, but I understand you had a deadline. The falling blocks fall in such a short period of time after you touch them that it makes having to jump on them from below and then off of them again immediately feel damn near impossible, which is what a lot of the later levels have you do. Especially when you knock them down when you hit them from the bottom.

I also really wish that you could use the A and D keys to move as well as the arrows. I am much more comfortable playing that way and eventually crossed my hands over my keyboard so I could move with my left hand and jump with my right. It's just a preference thing, but it's how my hands are trained.

The levels feel like they're the right length, and are challenging but beatable (eventually.) Good job!

p.s. Love! I haven't used that in a while, but it's nice to see it.
