The autoshooting mechanics combined with the dodging are really fun, and the visuals and music make it a great whole as you can concentrate on dodging stuff while deriving satisfaction from damaging the boss.
I had a lot of fun playing this one!
The starting cliff is virtually invisible so I ended up walking off of it several times. The rotating platforms also seem to get stuck on the rotating phase if you die after it starts, which makes subsequent attempts a bit more difficult.
I think this game would be helped a lot if you didn't have to do that initial walk back to the boss.
