Ah I love stories like this, apocalypse/post-apocalypse style stories.
Vanishing all adults off the face of the earth (and kids I guess? havent made it that far yet if otherwise odd choice but I wonder if Red's power is a multi-dimensional split, where Adults go to dimension A, R-19 = B, R-11(?) = C would be a fun idea overall) but MC ofcourse starts out with no sign of a power (typical trope) but if you pick a nifty option during a scene that you PROBABLY wouldn't have picked the dev kinda did hint at what his first power is

I thought it was a little too fast for something to be missing personally especially from someone with
enhanced strength that just pummeled you and you walk like nothing happened
I do wish though one of these times I would play one of these the MC would just have an absurdly stupid power like controlling electricity, object manipulation, full blown telekinesis, yadayada.
Definitely good so far. Exciting.
