For those of us who would like to make an honest living selling the games that we've worked so hard on, the "freemium" game model has destroyed the game economy. Runaway deflation means that it seems that very few are paying for games outright anymore. Now the fees are hidden. Either the player has to be subjected to a stream of ads or is nickel and dimed to death to get upgrades that would have been included in a game of yesteryear. Of course there is no one to blame but the game designers - us. I saw the same thing happen to the book self-publishing industry. To get high ratings, people started selling their books for the lowest price possible, even going so far as to give them away for nothing. It's a sad state of affairs for those of us who have families to support and who would like to be able to make a living doing something we love. Is several hours of entertainment worth a couple of bucks? I think so. Think about movie prices - $10 bucks for 2 hours (or less) of entertainment. I'm offering several hours of entertainment for 99 cents. I remember when all video games came with premium price tags but now consumers are spoiled and don't want to pay anything for their fun. Can you blame them? I guess I'm unusual in that I still don't mind paying for video games. I PREFER not having ads shoved down my throat while I'm trying to relax and I don't want to pay for upgrades that should be an intrinsic part of the game. End rant.
It is strange that there is this pool of videogames that are free, and yet they make so much money. Players spend money on the choice they made freely. If it's something they enjoy, then they are willing to spend money on advancing their enjoyment.
Does the freemium model suck? Oh Yeah. The times have changed and with it, the industry has too.
Btw, I played your game. You need to realize that the app store is vast and people look for exceptional art work first. Your heart was definitely there with the game, but the art work is not. It's not your fault though, creating good art work is difficult, and hiring artists is expensive.
