Prototyping & Placeholder sprite sets

Today i'm launching the Prototyping & Placeholder Sprite Sets. The largest problem i have as a developer is remaking graphic assets every time i start a new project. All i want to do is get coding and make a game but i'm always stuck working out the graphics to just get the gameplay functional.

I looked online to see if there was any prototyping, placeholder, template, basic programmer art sets but the ones I did find was limited. So i made my own and here is the first set "World". There are 4 more sets to come aswell as plenty of updates for this and the other sets. Please leave your feedback, suggestions and any issue you run into and i'll do my very best to improve these asset sets as i use them and hopefully you use them too.
