This was a pretty fun freemium game when it was released. I never sank a penny on this game just cause i'm not a fan of IAP. sure people defend games with IAP's because it supports the devs but i'll support the devs anytime when they release full games.
Unfortunately people got burned by this because they released a full version for 4.99$. it's funny cause i was going to buy this game when they did make this a full version but i forgot all about it. it's awesome i did because 99 cents is even more better.
