I love this platforming mechanic!! It definitely has a bit of a learning curve and I think thats in part because of the control scheme for me personally. I feel like being able to rebind space to jump and spin to something else would make more sense in my brain. But I love the concept of this and after I got used to it, the gameplay was very captivating. The first time I pulled off the launch with the hammer I had a mini wow moment. I would love to see you develop this mechanic further into a full project.
Also that fail screen is hilarious. hammer guy is such a little goober
