I love how the visuals on this game are made and executed, like the Youmu's sprite, the explosion, and heck even the grass is animated XD. It is a nice game, but I think it needs more enemy variations. After you realize that it's only the ghost that chasing you wherever you are and the Kedama is only chasing you when they are inside your screen, the is no longer difficult since as long as you can kill the ghost fast enough, the rest of the enemy, that being the Kedamas, can be wiped easily.
I played the game until stage 3 or something, but I'm not sure if there's an end to the game so I stop. Good job on the game though!
I streamed the game here around minute 84 if anyone wants to watch:
