A platform game made with Unreal Engine 4 using a custom-made 2D platformer kit.
The player has the ability to destroy the world around them which can make things both easier and harder to accomplish.
The maximum world size is massive, almost infinite. Though I still need to do more work on this if I decide to make a game that will be played in an almost infinite world. Here is an example of a massive world where each pixel is a block. Here I have set a maximum world size of around 2000 blocks across by 600 blocks high (I can’t remember the exact values I had for this zoomed out screenshot).
