1- the red liquid and the invisible men are a secret and is going to be expanded on in the next updates (after the Jam ends).
2- the text on the screen is static because i didn't have time to finish it.
3- the theme of the jam was Empty but not alone and the invisible men was watching you all the time (you can find the but its very hard)
4- i was planning for a better experience but i was a solo dev on this jam and i ran out of time.
I'm very pleased that you were able to finish the game i didn`t think anyone will get to the end.
