I'm glad you enjoyed your time with it! I also wish it wasn't so short, but the lack of substance I had caused the gameplay to be pretty stale pretty quickly. I ended up making a last minute change to the shop costs and achievements to help relieve some of the monotony. Sort of me being lazy but also I got done what I wanted to accomplish with the project. It works, and for my first completed attempt at a game it was a great learning experience.
I 100% agree about not having the image(s) and the main interactive part of the game on the same screen. If I returned to this concept I would restructure the game in a more "traditional" landscape layout.
