This is...
Not a fun game.
"here's a field of 1M+ light unlocks, you can only earn 1.4M light in a reset, and that reset takes a really REALLY long time of doing literally nothing because you've got everything" is bad.
"You got a pristine light! And nothing to do with it" is bad.
Geezus.
Like why would I even want to play past this point? You've designed a time-wall that lasts for HOURS of ACTIVE PLAYTIME.
That is BAD. REALLY BAD.
Null Essence just sucks.
It's literally "I paused the game 'cause you weren't looking at it" until you deal with it long enough to get to "I paused the game 'cause you weren't looking at it, and now I incentivize you not to look at the game by 5%".
It's actually the WORST feature of an already bad game design. The "don't play my game, so that when you do play my game it won't suck"-feature. That's literally all it does for the player.
It's the worst.
