Lovely-looking game. I really enjoyed the art and effects and how that contributed to the theme.
Gameplay was fun and interesting, but I felt kind of "thrown in there" when it started. A tutorial would have been awesome to have. This is awesomely put together for a Game Jam game, but even something as minimal as a screen displaying the controls (or even a simple text object) at the start of the game would have been really great to have.
There was also not a huge sense of level progression. Your description says that there were three levels of this game, but I only ever saw the first one. Admittedly, this was partially due to my lack of skill at bullet-hell-esque games, but also because I quit before I knew that this wasn't just an "endless mode"/highscore-oriented sort of game. There was no immediately apparent way for me to tell how far I was in the level, or what the overall level goal was (kill this many enemies, survive this long, reach this point goal, etcetera)

Otherwise, this is a very nice game. I give it a well-deserved 4 and hope to see more awesomeness from you in the future!

This is a nice game! I love how it auto shoots and the simple graphics that are hand drawn! Its quite a simple cool game. I made a shot Let's Play of the game, if anyone wants to check it out...

Awesome game. It's kind've confusing, though.

The art style and level of polish are very impressive. :)

LOVED IT! 5 Jolts Gameplay, and music was good!! altough imma noob at it hehe >_o

Cool graphics, mundane game play.

Found it brilliant on yoyogames, find it brilliant here. 5/5.

Too much like Ad Nauseam. I don't like it after about 5 minutes.

Cool shooter, but a bit hard with that amount of hitpoints.

Awesome game ? Yes, always liked paper stylizations and cute shooters.
Perfect game ? No, ther are still some room for improvement:
1) Once again, whole action is consolidated around abusing poor ‘Z’ button. If there are no limitations to fire constantly, why not enable auto-fire option ?
2) It was way too short – I only started to get really excited on level 3 and eventually game just ended with nearly-mocking (yes, I like it too) request for playing again.
3) Sometimes It’s hard to navigate through constant screen shivering and dodge words on the night stage. Also, lost hearts should be indicate more clearly (different color f.e.)
4) It requires some (too much for casual game) time to get that you can move vertically as well).
