Hey, thanks for taking a look at the game!
To be completely honest, I don't really have any plans for early access at this moment.
I'm more into the release when done method.
I'll take a look and see if I can make the missile room a bit easier to figure out, added to the to-do list. ;)
The marker on the map idea is a really good idea, I don't know how I didn't think of that already, definitely added to the list, thanks. :)
I'll add the resident evil map thing to the list as well and we'll see if I do anything with that.
Anyway, thanks a lot for the feedback and glad you like the game! ^^
