There later could be some items like suction cups for glass, and then you could make more complicated and progressive levels, like ''you can't get there before you get that item'' 'n stuff

Yeah that could work! I have some ideas for items I might implent for sure.

Not sure if this is already something you can do but if not would be a great add for the editor, but a toggleable "snap" feature to snap corners of objects to make things easier to line up. or a way to type in a number unit for xyz so that all your pieces match up properly.

since i see that you are open for suggestions, maybe some kind of grapple hook would be cool! Either a hook that you throw or a gun-trype model that only attatches to a certain new block (maybe orange? idk). just an idea though.
