Hey ! I personnaly had some playtests for my game but also for testing level parts I made sure to spawn the player at the highest I achieved each time I made a new part of the level, I was struggling at first by the punishing aspect of falling but now I became good at my game and manages to end to the top one every 2 or 3 tries if I play safely, still I fail a lot when I speedrun but I am starting to get decent times I feel!
