In my experience in the shoot em' up genre, the ability to freely explore is not really anything I have ever come across before. In a genre typically filled with chaos, this was a pleasing escape from all that. The casual and artful direction this game takes makes the conversation of balance and sequencing an interesting one. On the typical shmup game I would immediately say there is some difficulty 'losing', but I enjoy that the game is majority an art piece than bullet hell in that regard. To make add that extra level of tranquility, any background music and/or sound effects would be a nice addition.
