A Better Death Penalty
The current death penalty for the game is not really that bad, or hard to avoid. Especially on survival where sometime is is easier just to save your inventory by entering your base, life pod, Cyclops, eat some rotten crepvine and die. I think it would be a bit nicer if you always lost the basic material i.e. ores, seeds, plants, and the also lost the more complex items that had not been saved in the current system.
