Thank you very much for your comment!
Unfortunately, we didn't have enough time (and recurses) to make a better blendtree of animations. Mixamo has a lot of animations, but not the ones we needed, and didn't have time to do them ourselves. We will try to improve them once the jam finishes.
The plates have to be activated in a determinate order. We know we have to improve the feedback to the player, and we will work on it.
Thank you again for your comment. It helps us a great deal to know where we have to improve.
