so yeah I downloaded the practice mod from the site, installed the clear superliminal version from steam, installed the Melon 0.5.7, but when I launch a level it turns out that there are not some of the functions. like it cant show controls (when i press H too), cant spawn objects, etc. if you dont understand what Im saying, here are the screnshoots how it must look (from youtube video) and how it looks at mine. hope you can help
Those features are only included in the legacy practice mod, not the normal practice mod. If you want to use those features, you'll have to downgrade your game with the 2019.11.12 downpatch, and then install the legacy practice mod. You should be fine without doing that though, since there isn't much more that's missing besides what you mentioned.
