Yes I'm sure that's not the way it's meant to look, Enemy shots (snowballs) are near invisible and the background moves constantly. Try the attached savefile, first savegame, last level is called "?TUNNEL?" - which reads kind of wrong, too.
All in all this runs a whole lot better than that old version from the "appstore" and is heaps of fun. Thanks a lot!
Edit: The charge beam doesn't charge, but fires away constantly.
Edit2: Is it tyrian an easy shooter compared to others? I am a side scrolling shooter newb and suck at other games of that genre, but here I progress rapidly. Episode 4 now, almost maxed out, only like two or three levels gave me a hard time. I'm playing on normal with slow movement. Maybe I should go faster...
Edit3: We need Powermanga on the repo!
