Thanks! I'll think about it. I've just started implementing checkpoints. Making it so barrels and collectables don't respawn after loading a checkpoint makes sense. I think I'll try it out and see how it feels. On the other hand, they are kind of meant to feel like coin blocks in super mario. You can collect coins if you want to, or you can just run past. If you die before getting to the end of a level, you rarely go through it slowly to collect everything, you usually just run to the end, to get back to where you were. I'll have to experiment with it a bit and see which feels right.
