I became rather emotionally attached to my party on my first playthrough. I won't say more.

Really enjoying this so far. This is absolutely something I jive with.

I'm really only having one annoying issue, and that's that the UI generally doesn't seem like it explains what you're doing.
The battle UI especially is a bit confusing, as I struggled a bit to figure out what my squad's special actions were, and in the middle of traversing I had a menu appear that didn't give me any context as to what I was selecting my survivors for. A bit of text could go a long way to better explain such things.

It would seem judging by the credits that English may not be the first language of this game. I've noticed a couple typos even within the first couple minutes of play.
During the food event where you enter a forest, one of the lines is mistyped as "nature inviting you to take place your place in it"
One of the pre-battle texts has a small double letter typo: "...the eyes of someone that's *alreadyy* given up on life"
During an event where you meet a survivor with gas, the phrase "I took all the (things) in this place" has "on" instead of "in", which felt a bit weird to read aloud. In that same event, when you accept the offer the survivor makes, the word "their" is misspelled "Tehir".
During an event, the "continue" prompt was untranslated from Spanish.
If I run into anymore text issues i'll update to mention it.

As one additional issue: the language select submenu has 3 duplicates of Spanish and English.

Kind of reminds me of FTL except it's a Web game now.
