I'm always impressed by smooth pixel 3D rotations for some reason. I think the difference between 1 and 2 hearts is too subtle, it wont be clear from all angles and if there is action going on. I would recommend he loose the jacket at 1 heart as well. Otherwise loving this, though I guess I'm still not a huge fan of the gray outfit.
Do you have a TIG devlog going too?
You are developing in Unity correct? It looks like they just released an alpha build of their new 2D tools, including a tile map editor.
Last. For the anchor swing, perhaps have him carry it around on his shoulder and then swing it down from there. I think that would look a lot better and would provide a more unique animation too, so he kind of bends down to slam it down.
