I really like the spiral shooter saying "Red" all the time. I think I died way too soon to find all features that you implemented.
Sometimes I died because a word spawned just next to me on the border. Maybe you could improve the game a small bit to remove the border spawn and spawn outside the border so the player would have a bit more time to avoid these sneaky words :)
It wasn't too deep on features, this was my first game I made and I just started programming =P I had 6 different things, the homing ones, the spiral, and then 4 wall ones that came from each direction. After that, they just get faster. Yeah walls are dangerous haha. I'm not sure how I'd work out that outside the boarder spawn, since technically, they all spawn outside the board (besides the spiral). Maybe a blink when something is coming from that wall? Like a little color bar, single pixel long or something?
