Mind if I post a translation of the description?
"Prototype of a "retro" first person shooter game, with a great emphasis on the game feeling. Originally developed as an entry in the gamejam Mizjam1 in 48 hours.
This first stage of development is very focused on polishing the character's control and gradually implementing complementary mechanics that are now queued."
Use this if you don't now Spanish. I'm not trying to insult anyone, I'm just trying to help people understand the description.
