Woo, probably your best game so far! :D And not just because I'm listed as Inspiration (wonder if you happened to stumble upon my old Tomatoo VS Caroot contest entry?), compared to previous ones the overall flow of gaming feels very polished and fast-paced, the levels aren't too hard, but if you want to get everything right it's a bit more challenging, and shooting the vegetables is a pretty rewarding task. I like how after the first boss you need to aim at a certain length too, it's a nice twist. At the second boss though (the hand) I fire a stream of bullets, the hand disappears and... that's it. I'm stuck on the level! :/ Bug?
A few suggestions: you could make the 'Next' text clickable as well as the icon, I clicked the text first so maybe other people do too. For the introduction, how about letting a user click past each cutscene rather than wait for the timer to run out? Especially useful if you've already played the game before and just want to get started. Anyway, nice work! Keep it going!
