Introducing Tile Hill - a tile-based sort-of-side-scrolling proof-of-concept platformer in Pulp!
I adjusted the jump curve to feel more natural, and made the jump height with the A button depend on how long of a run up you take. The B button always does the smallest jump so you can still hop at speed. Also - semi-solid platforms!
I added slopes that can be run up-and-down. You can also press down to slide down a slope!
Spikes are, naturally, deadly to any platforming hero. I also made some circular saws which aren't in the demo but are in the editor - the difference is that spikes are only deadly on vertical collisions, but the saw is deadly from any direction.
Finally I added springs. They preserve vertical velocity, so you will bounce off them up to the same height you fell from.
Here's the JSON if you'd like to play with it and see how it is put together
