This is a really dangerous game, it's really tempting to just sit and play it again and again and...
Graphics: So-so, but who notices? They do what you need them to do, most of the time all you see is a blur going past anyway, so what really matters is that you can tell the stars from the trampolines, which you can.
Style: Seems pretty consistent here. Again, you don't notice it much, you're too busy trying to get higher (or stay in the air).
Sound: Speakers off, sorry.
Violence: Not much of it, but the splat at the bottom is nice.
Interactivity: Wow. This reminds me a lot of the old send-the-guy-bouncing-to-the-right game, but the ability to hover and move around adds enough control that it doesn't feel like you're spinning a roulette wheel and waiting for a result. Even when you get unlucky, you think, "Man, if I'd just timed that a bit better, there might have been another trampoline up there!"
Humor: Again, not much, but it's a bit amusing to just hit the Kill button for no good reason. SPLAT!
Overall: Very nice game. 4/5. I give out 5's very rarely, so that's a high mark. Well done!
