there's a momentum system where you can build up speed similar to super mario world. Animation shows speed and top speed is the full run motion. If time wasn't a restriction, unique background tiles would have aided collision recognition instead of simply shifting the saturation. I tried to make sure there wasn't anything critical when it looked the most confusing to cross a background tile.
not sure how you're getting your movement locked, even momentum from damage is a single impulse without removing the player's ability to adjust. worst part about these comments is hearing bugs you have no idea how to recreate and fix
Thanks for playing!
