@wjt @JanusCross15 I see two options here:

1. The boxes could be pushed without any grid constraint (like in this prototype or in MINIT).
2. Or, the boxes could be pushed in a grid (with an AnimatableBody2D node maybe?) while the player move towards the box or use the "repel" action on them.

I think both have potential, it all depends on the kind of puzzles we want. Maybe 2 can open up more possibilities for pattern-based puzzles? Check this level for StoryQuest "Gazzart" that does the latter: https://game-lab-5-0-utp-group-6-team-3.github.io/threadbare/#quests/story_quests/gazzart/2_game_castle/gazzart_castle

@med-bc and team, if you can help us understand how you did the boxes puzzles, that would be great!
