Okay. Great game so far but...
How did Apple let this through out of curiousity? It's letterboxed in iPhone 5s! Thought that was against their rules?
Also, the train went by with one cart and then nothing else appeared for 2-5 seconds until train carts came without a train kinda pushing themselves.
Overall to be honest I don't feel like it's quite yet polished. Here are some suggestions if you'd like:
Seriously make the iphone 4" screens fullscreen. It doesn't take much and it's against apples rules to not be full screen. I wonder how you got by?
The train carts feel funky, not sure why, but I feel that aspect could be tightened up a little.
Better looking fonts. I get my fonts from
http://www.dafont.com they have great commercial use fonts take a look!
Don't know if you want too but I always feel like one touch pickup and play games should be in portrait mode with the exception of games like Tiny Wings (Tiny Wings need scenery) This is because when I want to play a pickup and play game I'm usually waiting in a lobby or something. So I just want to pull it out and play, not have to use two hands to hold my phone and play if you know what I mean?
What I like: I like your art. It works well. Your sound effects are nice as well.
Your concept needs a little work but I like the idea. Good luck guys! I just released my first game and I know how hard it is to even get close to a decent amount of play/downloads.
