Sliptastic,
Don't worry the ending wasn't revealed because the project is launched on Kickstarter to finish the game. There is more to the game, but wanted to see what the public thought before launching the Kickstarter. Thank you so much for playing my game, and I'm glad you enjoyed it! The final project will have more puzzles, in-depth ending, backstory discovery, & more player interactions. Awesome job at beating the game, and thank you for sharing your experience.
Thank you,
David Clark (Promnesia Developer)
