That was a fun game! Things took a little getting used to, but the three different arrows were all unique and interesting. I think the impulse arrow was my favorite, because it felt like Halo rocket jumping. That was a little hard to understand based on the tutorial level though, it was by accident that I actually shot it at the ground and got launched up.
It was also kinda tricky to figure out the final boss at first. "Space to Jump" made me think I was completely missing something because I'd already been jumping. Maybe if you attach a hookshot to either of those to nodes in the boss room, the floor could drop out and leave you hanging.
