download final release here gmd source included
Was bored, started working on a shmup. Vaguely like scalegunner, except that this is significantly less ambitious enginewise and I'll be a hell of a lot more likely to work on it if it involves less work to work on [how's that for a sentence?].
Polished it up enough to make a release of sorts. Currently has 2 stages. Graphics, patterns, music, etc. all subject to change.
Press F1 for help.
Controls:
Mouse: move - move cursor, left button - fire, right button - bomb
Keyboard: WASD - move ship, space - fire, tab - bomb, shift - slow

Here's a pic. Looks an asston better in motion, seeing stills of this is embarrassing.

Visuals, audio, and code by me. Made with Game Maker 5.3a [thus, whether the display is filtered or not is entirely up to your video card, sadly].
Should run on machines running Win98 or better. Might need a semi-recent PC though [because GM is slowish -- I'd up port this to Studio, but that's more work than I care to and Studio's build times are awful anyway].
