Good text. The idea of alternating PCs is fascinating (reminds me somewhat The children of time).
Viewing post in The Prison of the Star Sovereign jam comments
The fact you interpreted them as alternating characters makes me yet more afraid I couldn’t get into the text, what the dungeon is.
I hope at the table something of the cosmonauts the players explored before will be transferred into the medieval fantasy heroes. Tbh I couldn’t playtest this in time :(
