Love the sprites and the music use. There's nothing better than Youmu holding her hand out as her sword remotely does her bidding.
It took me a while to figure out how to get past the first wall because double jump wasn't working for me. I didn't realize you had to wait for the character to be falling (rather than rising) before you could do the second jump.
This is similar to the other idea I had for the jam. For my idea there would be at least five different abilities and they could be chained together in different orders, so like you'd have a homing amulet that bursts into swords that shoot lasers for example. I knew I couldn't make that in the jam's three days, but it was fun to imagine how silly it could get. XD
