[Rant-on]I really hate when people use the tiles as collision boxes[/Rant-off]
Great entry btw! I really couldn't get past the spikes with arrows part, tried more than 10 times! But besides the rant I think the game concept is ok (who doesn't love a jetpack?) and the animations are excellent. Sound feels really appropiate and the parallax effect is nicely achieved. Is the art yours? Really liked it! Congratulations!
