I've seen your comic @Somedark , and I will raise it a review,
Fantastic start to a perfectly intriguing plot as I want to know more about this substance and what its doing to the astronaut.
A lot of its plot sort of reminds me of the film gravity, plus the alien substance almost makes me think of venom. Could either of them have been an influence? Just wondering.
Your english was good by the way, don't worry too much about the spelling errors. Believe it or not, you're clearly a lot better at learning English than I ever was at learning French.
