I read the other comments and your replies, and I think you got the arcade feel right. A lot of people will be nostalgic when playing this, but for a newer player, I would recommend adding a different mode. I don't know if it would be easy and hard, or modern and arcade, but having the two options would really widen your player base, and I think it's worth it.
I didn't see anyone else mention it, so it might be a problem with my speakers, but the music seemed a bit loud.
Love the dog with the shotgun.
Since there are only a few days left, I am rating and giving feedback to games with few ratings. I would appreciate it if you rated my game too. No need to leave comments, unless you feel like it.
Thanks for the experience =]
