It's fun an addictive!
Needs some tweaking though:
-starts too soon. I don't think it needs a tutorial or anything, the enemies just need to appear a little later. Give the player some moment alone or make it face a really easy first enemy. That will give time to figure out the whole thing.
-When I saw the item that decreasses your fire I thought it looked just like the bullets itself. that made me arrive to this conclusion: red bars make my ammo stronger, green crosses are HEALTH. but I was wrong! You have to be very clear here. There's no need for subtlety on this kind of games.
-Needs a health item.

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.
