I like the concept behind this game quite a lot! Although there are some issues with how the levels are designed (versus Shinmyoumaru's ability to navigate them), as well as some enemies easily blindsiding or otherwise landing what might be considered cheap hits, the jam's theme was used in a fun way between the powerups and the overall idea of scaling a tower.
I also liked the visuals quite a lot. It's not often that I see castle-like structures like this. ^.^
