I recommend you try to beat the normal version first, since the timing is supposed to be part of the game, but if you absolutely can't do it, here's a 50% slowed version (updated): https://auroriax.github.io/PuzzleScript/play.html?p=498c0db3382c07ea6ec88eb265b6db82
Making a stepwise version would require a lot of reworking and also completely change the game, so I probably won't do that. But thanks for the feedback!
