if you are watching the video on a 32" lcd then of course it will look blurry and also the video is not HD.
i have purchased those graphics and they should have a pixel look. they look very nice on a 10" tablet and on my samsung galaxy s5
i have purchased a lot graphics with higher quality. after i will finish this platform game i will make another platform game with different graphics.
i design my code so i can use it in other box2d games (thats not that easy, but i make very good progress)
i am now working on the menu, the game mechanics are very good after i finish the level selection menu i will start adding new cool stuff.
then i only have to add new levels what should be very simple with Tiled because i create there also object and my code know how to handle them so it will be
almost a drag and drop process for me
i must say i felt in love with box2d and libgdx. you get great result with it. it is not always simple you have to google a lot and read a lot tutorials (and i dont like to read) but you have a lot satisfaction when everything runs well on your phone.
i have about 4-5 box2d games in mind i want to publish in 2017.
i will also open a different google account where i will put only games (box2d games)
