I haven't played it yet, so for now I can only answer the page question. The opening of the description does a lot of work, "You wake with your fist closed around nothing" sets the mood better than any feature list would. One small thing I noticed: your post says the game is complete, but the status on the page is set to In development, and some players skip anything marked that way, so it's worth switching it to Released if it's done. The bullet list under "The practical part" also looks a bit bare, since items like Turn-based combat and Cave travel have no line after them, so one short sentence each would help. Having the 3 to 4 hour length and the content warnings right on the page is a good call too.
The cracks spreading across the screen after your worst failures is a really cool idea for a text RPG, congrats on finishing your first game.
