On paper I liked this, but it mostly boiled down to "can I place this somewhere so that it overwhelms red" (lvl 3) and even when that happened, I didn't feel clever. That might be a me thing and I just could have missed smt.
Also got a panic after finishing the 2nd lvl, so I had to restart:
robo-swarm-e8d49bb8f1a19b2.js:412 panicked at src\draggable.rs:37:59: called `Result::unwrap()` on an `Err` value: NoEntities("bevy_ecs::query::state::QueryState<(&bevy_transform::components::global_transform::GlobalTransform, &robo_swarm::levels::WallCache), bevy_ecs::query::filter::With<bevy_ecs_ldtk::components::level_iid::LevelIid>>")
