Utter rubbish - the screen kept going white and I couldn't see anything! Not only that but you'd have to be inhuman to be able to type as quickly as some of those ninjas, and that was on the normal level.
Yes defo need grey tiles that go anywhere, or extra lives or save function - this is nigh on impossible to finish otherwise, and INCREDIBLY frustrating. 3/5.
