Just a test, not worth looking at. Shared so I can work with Turbowarp easier.
Everything except the textures are completely mine so far. I thought I could do this better than some of the other options on Scratch. Things to work on are entities, generation, collision, swimming, liquids, everything except movement, animation, and rendering. I have finished the basic concept on paper, if I can gen generation and collision working I'd probably have enough motivation to bring it to modern feature parity. Of course, I almost certainly won't get generation working, I don't know where to start. Collision is going to be trouble, I have a hacky way of doing top and bottom block collision, but for whatever reason it doesn't work at all for horizontal movement. I still think I could figure it out though. You might notice how you can jump two blocks, that's on purpose, I feel it'll help 2d terrain stay out of the way so you don't have to terraform your whole world to be perfect zigzags.
