It's Cat-sle, not Cas-tle
He is a cat after all.
good god this game looks bad. Really an improved jumping and shooting physics engine would have been all it really needs to be more fun looking. Please tell me those sprites aren't ripped from castlevania or something similar. Anyway if the sprites are indeed original they look pretty darn good.
Music....so bad. I'd be tempted to play it with no sound and put on some mp3s of something better which wouldn't be too difficult to find.
The artwork looks like they re-hired the guy who did the box art for megaman 1.....I actually like that it's a good thing
