Hive fortress is good, but this one thing feels bad

Clearing the fortress is great! Hunting for the chests to collect, clearing the map to make your escape when its time, then fighting off the waves of enemies that run in all feels great!

What isn't great is when all of the waves are cleared and the first damaging blast that triggers as you're running for the exit and it kills you. Then you have to respawn, go back to the map and the lady says you did it, but you get zero loot. That feels so bad.

Why do I get no loot for dying during the escape? The hive is still destroyed and I can go back into the map.

Can an escape guarantee some form of loot as a reward?

Maybe the strength of the wave should increase over time so there is incentive to rush to the exit?

Either way, the first damage blast shouldn't 1-shot a player with full hp and cause the player to lose everything for the time commitment they just put in.

That is the only change I would make to hive fortress.
