Thanks for the feedback
I didn't mention I have spent some time thinking about the weapons system. I liked how X-Out you could choose the weapons before playing the level. One of the frustrating parts of some shoot em ups is not being able to customise what weapons you can use for each level or losing all weapons when dieing.
If there are particular elements of shoot em ups you liked, please let me know. I like for example how you could move horizontally and vertically in Blood Money.
Hi Giovanni, I possibly could help you with some graphics (may already have some sitting around ready), send me an email and let me know more details. I'm always willing to help out other Amiga developers, thus far I haven't asked for any money. If I can come up with some graphics in a day or so to help you get going on an idea.
