First of all, thank you for opening this. I've spent the past 6 months or so working on this, as all I have right now is a Windows 7 Dell laptop and an iPad. I'd love to buy a nice desktop to make real games on, but I just don't have the money for it (yet).
Essentially, this is a game engine, with a custom text serializer and deserializer, which I titled Omni. That is used not only to save progress, but to create game files as well.
If you want to save your progress, you might need to Fork this repl. II have not had the chance to test it yet though. If you save your progress you'll be able to leave the page, and come back to keep playing later, as the game is a slightly large game, for a text game. (Probably only if you fork it though.)
I have created a sample game, which I titled "The Final Frontier". It is a game that takes place in space, with the objective of saving Earth from the evil space squid king. (Dont ask where I came up with that.)
Please enjoy, any suggestions or such are highly appreciated.
