I went through all the main stages and it seems that i only have encountered future introduced mechanics in side missions, that i haven't even completed using those mechanics, meaning those might not even be solutions for those. My bad.
I just finished the final main level, and it was by accident. I was just trying to make the path possible, and it just happened to be the solution to the puzzle. I don't even understand how this is the shortest path or one of the shortest paths.
It is ridiculous how puzzling a game can be with such few mechanics. This game gives off very similar vibes as babaisyou or N Step Steve, maybe with a little less depth reached with only 4 possible objects. It is the sort of game where i really wish i would come up with considering how simple it is. 9.5/10, there is always something to improve.
