Hey the death animation thing. Mabey if you have it set from an any state and have it activated from a trigger, and have the animator trigger the trigger from a onColliderEnter2D or onTriggerEneter2D statement in a script for on the spikes may fix it
Thought about programming a state machine, but since it was a simple game, I decided to do 2 blend trees: run/idle, jump/fall. Then, from anystate I created a bool for death animation. I'm not experienced enough with Unity Animator. I might try to fix this another day, but I'm exhausted right now haha
