Sounds fun and promising. I like the level select idea, what kind of theming will you use to differentiate them (nevermind, I kept reading: sounds cool)? I also like the risk / reward baked into the power bomb.

The Rank is very interesting, I love that the scope of the game is small enough to allow each level to have a variety of gameplay difficulties. 

The art design section is particularly nice, it shows that you understand what this game needs to be playable.

Overall I like this pitch a lot, it seems within the scope of a month long jam and shows a lot of gameplay knowledge/references that will help with implementation. Good luck!

Shoot'emups rule! Doc is great and having a prototype is even greater. I'm going to play this one for real when it's done!

All this sounds great to me! I think you've got a really rock-solid plan, I think your scope might be a little wide but it also sounds easily trimmed, and you clearly have a real passion for the schmup genre.

If I were to give two suggestions, I'd say:

1. If you have the time, I'd love to see some accessibility options (stuff like being able to put auto-fire on a toggle, decrease game speed, replace detailed sprites with flat colors for readability, etc.)
   Nothing in your document really jumps out at me as "THIS is what sets this schmup apart", it mostly just sounds like a further refinement of the formula. I concede that I'm not at all a schmup person, so maybe to someone whose more familiar with the schmup formula there's something that's clearly really different in there (I'd guess that bomb gauge?), but it didn't come through to me. Though, again, I really don't know what I'm talking about when it comes to schmups.
