Well, I bought the game and I gave it a shot. I like indie-productions like this.
The game is fun but I encountered a little snag where, somehow, it'd keep asking me if I wanted to resume the game constantly. I must be doing something non-standard with my thumbs and this takes away from the experience.
Granted, I play this on an iPad at 1x-mode, so the form factor difference might be the reason for the constant pausing.
Hmm, Not sure what the problem would be. Are you accidentally touching the top right corner of the screen? Thats where the pause button is, there's a little video player pause icon up there. I made that whole corner into a pause button so it's easy to hit when your playing on the iPhone
When I put the system at 2x and played the game, I made it as far as level 8 without a glitch. Then, all of a sudden, it kept going into a mode where it kept asking me to resume again. I play the game on landscape mode on an iPad Air, if it helps you any.
The game is fun.
My constructive criticism is more business related than game related. For $1.99, there are other apps that give you a lot of strong competition. An ad model or some other addictive mechanic that employs IAP once people have it in their hands might work better for you. Also, more people looking at it will get you more feedback, and that'll guide your future development as a developer.
Regardless, I've added your blog to my list of blogs to read. I'd like to see you succeed in your efforts, whatever it is you try (if you continue on this path.)
