Hello César,
Given the Install Instructions, it seems that you meant to include a .gb rom file download. However, I am not seeing any on the page. I am looking forward to playing.
Thanks,
Ben
Hello Ben! I haven't add a ROM file yet as this is in a pre alpha state. I am figuring out how to create an intuitive turorial for the game (as of now the is a lot of confusing and boring text at the start of the game) and finish up the remaining levels so that it feels more complete. I hope I get some time soon to continue this project and finally upload a true "demo". Thank you for the interest :)
