No, I send Steve a cheat version so he could go through to check the whole thing no problem. The version I have here to download is the no-cheat version. Let me know if you, or anybody needs the cheat version, I'll make it accessable. I actually thought people could breeze through the game, as it's not that hard. Of course, I know some tactics, and maybe that can help. :) I saw that Steve didn't include the bonus level, maybe he didn't find it, and that can be an immense help in the first playthrough.
There is a second and third playthrough with extra enemies, shields and bosses have extra HP or some new or stronger attack forms. But don't worry, if you play it through once you saw everything. Higher playthroughs only yield different colored name in the high score list. :)
