@Luatee - I ran across another user who has this issue. To fix it, I presume that you just need to uninstall and reinstall the app.
I’ll give it a try
@Luatee - What device do you have? The only explanation I can come up with for the crash is an OpenGL error.
Just a quick update: I’m #96 on all GameCenter games, so you can go to the featured page, click on GameCenter games, and scroll down a bit, and you’ll see me.
Also, you can see me under Games>Puzzles.
@Zoyt ís this your first appstore app? Because if so your app is doing really well
@Zoyt, nice! I’m just waiting to see you featured on AppAdvice 
@Jessevanderheide - Yup. Thanks.
@JakAttak - Me too, but I’m starting to doubt I will because it’s released during the holiday season.
@Zoyt well I uninstalled it and now apple wants me to pay again!
@Luatee - Hmm… That shouldn’t be the case. Are you sure you’re signed into the account you bought it on? If so, try going into the purchased section and see if StackIt is there. Sorry for all the issues. I’m trying to find out what caused this.
Also, what device do you have?
Well it said I need to buy it but it appears to have redownloaded itself despite me not pressing any buttons… It still crashes but either way… I’m on a 16GB wifi model, iPad 3
@Luatee - Strange. Check your PM.
App Store does that. Hit yes then it will say that it has already been purchased.
Just grabbed it and reviewed it! Great game!.
@Briarfox - Thanks a lot. Every purchase helps a ton (despite the fact I only get 70¢).
@Zoyt how many sales do you got? It seems a lot of people have bought it
@Jessevanderheide - I’ve made 28 sales (as of 3 AM this morning, my time), but I also gave away 7 promotional codes, so really about 21.
@Zoyt It just takes 28 sales just to make it into the top 100 gamecenter apps? Wow!!!
@Zoyt 21 is still good, are there any sites that did a review on the game. Maybe that will bring some more sales in your pocket
I really like this game, and not only because I’m the current number 1 in 4 out of 5 rankings xd 
I really like it, will buy it asap @zoyt
@Jessevanderheide - I’m trying to get TouchArcade, AppAdvice, TUAW, and MacStories. I haven’t had any reples yet, but I’m assuming that’s because it’s the holiday season.
