Thanks, that's all great to hear!
The bunny pickup is intended as kind of a "tutorial puzzle", I guess? Since you can't move into it, it's supposed to teach you that you can pick up items with the mouse straight from the world, the same way would would pick them up in the inventory. In retrospect I should definitely have added an obvious barrier to make it much clearer that you weren't supposed to be able to step into that space, rather than relying on "it's just slightly too small".
And ugh, looks like you're right about the control rebinding; it works fine in editor, but I guess I must never have tested it on a player build - that's annoying. Thanks for letting me know!
