It takes awhile to get used to the controls. Thank you for having different options. I was impressed at how authentic this was to the game. Then again, I've never played the game. Well, I've seen enough parodies to understand it. The music's great too.
You get all the unique enemies from the game too. It wasn't too hard for me. Even the opening cutscene was great. I think the smaller image works. The sprite work looks better that way.
