Thanks so much! There's definitely some Pikmin influence here, it's one of my favorite game series!
Were you using the 1.0 build or 1.1? The 1.1 build contains some bug fixes that should prevent objects from clipping into walls and the floor, along with making both Q and E work for the object drop-offs. If these issues found a way to persist into the 1.1 build, let me know!
