Thank you for your feedback! Could you elaborate more on what you found sluggish? Was it related to the character speed or more to the swinging movement or something else?
The crates have colliders but for some reason some of them randomly fall off the world lol. This didn't happen in the editor and only after exporting the game, so i didn't have time to correct it after the upload. I should have probably done more tests on the target platform lol.
