Don't despair though. Touch Arcade is the best place online 'out there' for starting the promotion of, getting feedback and getting advice for your app.
Awesome family of strangers here! LOL
For example; because I tried the game, you now understand that the jumping mechanism, although easy to learn, may give problems to some players (There are some stupid people out there. LOL -Kidding!) and that you might need a little extra instruction in the app or in the description at the App Store to keep the negative reviews away.
There's a lot of information here on promoting your app as well.
When it comes to reviews that you get from people that you've given promo codes too; take advantage of it.
If there's a specific part of my review you liked, or someone else's, use it. (Ask their permission first of course.
I've never seen someone say no.)
If someone writes a specific statement in their review that you like, when you promote your app elsewhere, i.e.: your web page, face book, iTunes description..... use that statement.
I'll start with the review I wrote for you as an example. This does not mean I think it's a great statement, or not... just using it as an example.
"A guitar playing guide that shows up anytime out of nowhere and a little girl in pony-tails with a sword and a shotgun. What more could you want?? - Touch Arcade member; Lavender
"Cally's Caves 2 is pixelated goodness with just the right amount of challenge, frustration, & cuteness. The fun is worth the download. " - Touch Arcade member; Lavender
"I had a lot of fun with the original callus caves so will be checking this out for def." - Touch Arcade member; Cloudpuff
" It's a cool platformer. It has a lot of cool little things that makes it more appealing than a number of other platformers on the App Store." RampageDeluxe member of Touch Arcade
Use partial reviews from different places. Just don't take them out of context because it is just rude.
