I liked the humour of this game, and it felt smooth as far as I played it (the lava stage) however, I can't say that I liked the game overall. The music gets repetitive very fast if you don't clear a certain stage fast enough, so perhaps more variety within each stage is required. Also the sound effects annoyed me, however when I turned them off, everything which had been accompanied by sound effects before seemed like an empty action.
When I was playing the first stage, the spike one, I noticed that sometimes a spike would go into my character's head, and I wouldn't die as a result. This seemed to me like bad collision detection, as he would have to be wearing the world's most spacious hat to have avoided death then.
In the water stage, I jumped down into receding water, deep enough to cover my character's feet, and dissolved in it. It was at this point that I realised where I had seen this character before. He is essentially Link from The Legend of Zelda. I don't mind the reference, whether or not it was intentional, however, I always disliked that someone like Link couldn't swim in some of the games, at least not at first, and I disliked it here too, even with the cheeky explanation given.
Finally, it seemed from the very start that it should have been a game where you could drop down from one of those ledges that you can jump up through, with the S or down key. I do appreciate that this would have made some of the challenges presented trivial, however I disliked that this game lacked that feature, when it felt to me like it should have had it.
