About this game art and design - it's beeing placed here so everybody can see it. It is heavelly inspired on the art of the recently published Gato Roboto (by doinksoft) - that I've felt in love with. It was used due to two reasons:
1. I'm still learning pixel art so picking an solid art style was crucial due to time and knowledge limits - I can surelly say that this project helped a lot with it;
2. It did fit perfectly the style that I had on mind, besides beeing almost a perfect match with the other design choices on the game;
For the puzzles I came across several similar puzzles like playing games such as Runescape and even Pokemon (Gameboy & DS). It's a basic idea that personally I cannot find myself turning into a fully released game, but certainlly making as an easter egg or "arcade" side game on another proper game.
I took some time properly reading the kind comments bellow and I felt that I didn't managed to properly mentioned the inspirations for this project - wich is a big failure from my part as a designer in general - either by originally not mentioning wile posting this game or beeing unable to properly sending responses during the past few days.
By the way I utilized essentially 2 softwares developing this game. Aseprite (lovelly pixel art dedicated software) and Construct 2 (wich is a great engine for begginers and non programmers to learn coding logic or making basic demos for new projects).
