I'm impressed by the main mechanic - the way the bullets' positions scale perfectly when you shrink down feels like magic to me! I'm also a fan of scrolling shooter type games - and tasteful pixel art - so this was right up my alley. If I had one gripe, it would be that I'd often come out of being shrunk and immediately get hit by another bullet that I didn't see coming - I think it would help (and also just feel cool) to add a bit of a pause effect when you unshrink so you can refamiliarize yourself with where all the hundred bullets are at. But hey, maybe that's just a skill issue!
