It's finished ! To be honest, I'm quite proud of the result. I had time to balance the difficulty and tweak the user experience.

Please tell me if you have any problem running the game.
For linux player, you need glibc >= 2.27 (so it won't work on older distributions, like Ubuntu 16.04). If it's your case and you really want to try the game, the instructions for manual compilation are here: https://github.com/PFGimenez/1rl.
I hope you will enjoy 1RL!
