I understand I could just download an old version, but as I'm sure you're all aware Don't Forget has changed a lot over the past few years, and I'm looking to get into it... would there be an equivalent time end spot for categories such as 'Delta Door' now that there no longer is a Deltarune Door at the end? At the very least, I would like the accepted versions on categories that utilize removed features to cutoff when the feature has been removed rather than tacking + on the end, since currently it implies these categories can still be played in modern versions. If I'm interpreting things correctly, the only categories that can actually be played on modern versions are the Starwalker Quest and Splat2D categories.

fixed and added a all puzzle pieces category for v2.5.0+ seems to be the only thing you can sanely speedrun in v2.5.0+ that we didnt have a category for yet
ofc splat 2d and star walker quest can still be done in v2.5.0+

I admit that I am currently unsure which update it was removed, but as far as I know the puzzle pieces are not in the current version of Don't Forget. Unless I simply don't know how to get them to spawn, that its. While I don't know which version they were removed, they are present in a video guide from 2.6.1 that I've seen, with my arrival of 2.7.0 not containing any.

There are 120 puzzle pieces in offline mode you can collect in the current version
