I really like the concept, and it's quite a nice take on the theme to have confined the player movement to the different rails.
Gameplay wise the controls and all feel nice, but i think there are still a few issues, most notable the slash attack where i found it hard to judge the slash rate as it didn't feel like it was synched with the animation, and the dash being foward only can be tricky when getting flung into other bullets while trying to dodge oncoming ones.
Now that said, the game is fun, and i really like the spritework, the main character with his sword looks cool as hell :D not to mention the ship boss with the sprayed painted skull !
Overall nice entry with an original concept.
Good job ^^
