Awesome looking comic-styled graphics. However I found that the bullet movement was quite janky to deal with and I often accidentally killed the hostage.

I enjoyed this :) Nice art and a groovy soundtrack. Also I thought the tutorial worked very well and fitted seamlessly into the rest of the game. The levels could be a bit samey though, and it might be interesting if the little alien-gremlins damaged each other. But it flowed nicely once I realized I could jump infinitely... I'd definitely play a fuller version of this.

Cool use of the theme, and I like the way you have to be thoughtful about where you place your shots. Artwork is great, nice one!

Lacking some polish, but an interesting idea. Nice job!
