Thank you very much for the varied and positively critical feedback!
We hoped using the highlighted mouse sign on the side of an interactable block would make it obvious enough that it has to be used to aim at objects, but perhaps it could've been improved somewhat. The conveyors are indeed extremely powerful when small, it's intended for speedrunning/skipping certain obstacles! Perhaps the camera could've shown more of the area in front of you when using one, so it's clearer where you're landing? We will certainly take these into consideration. Thank you once again!
