I don't run the game anymore so I want to share what I was working on before my retirement: In one of the last acts (I don't bother looking it up. If you run this game you know what I mean. The level starts with you having a box in front of you and the end portal can only be reached by cannons ) you can use a cannon to skip between two pink blocks to reach a checkpoint. This skip should save around 30 seconds at best but at least for me it was insanely hard. I hit it around once per 300 attempts. Much luck to y'all
