What would that be? All packs? If so, that would take over twelve hours and no one really has interest in that, and I don't want to add a category that's just going to sit empty forever. You're free to run it yourself and then post the run here or in the discord and then I'll add it, but I will not add a full game category to the leaderboard until someone runs it. Plus, they still add new packs sometimes so the definition could change and that would be hard to moderate.
I suggested this in the Discord and I’ll suggest it here. We should separate runs that use hints from any%. Create a new category called hints% because it’s impossible to beat a run that uses hint without using hints yourself.
Tower pack has been added. Daily Puzzles would not work as a speedrun and will not be added.
What about adding the "time trail" category? Counting how many levels you can complete in a set time would also make this a speedrun. It would also offer an interesting alternative running randomly generated levels that you can't practice before. (I haven't run this game yet because I didn't enjoy practicing the same levels to be good, but I hold all records in Pou Connect which is basically the same with random levels.)
Could there be a category for just the 5x5 section, not just the whole classic mode?(just like Iea8ue said)
There is already a Classic Pack: 5x5 levels category extension; you can access it under "Full Game Leaderboard", under the "Leaderboards" option on the game SRC page.
