Thank you so much for the purchase and the praise. It's worth mentioning that this version of the game is developed by a third party and not directly by any of the original authors. However, it's officially licensed and I have a strong relationship with the estate of MULE's primary designer as well as a strong regard for the original game and the vision that its original authors had & had intended.
Funny enough, technically, game saves (and loads) are implemented. I use them for testing quite a bit. They also facilitate the feature where a client can quickly reconnect to a network game still in progress--say if one's computer were to crash.
My intention is to incubate this feature for a while before exposing it through an interface.
I always consider if a new feature can be exploited, particularly in an online multiplayer game. I have already put some work into ensuring crystite is relocated every time a game is loaded. It was a fun challenge, because it can only move crystite to locations that don't contradict any of the crystite revelations up until that point. Unfortunately, I did not make that algorithm work 100% with Meteorite Strikes. I shelved it because I had to move on to other enhancements.
I appreciate the request. It's definitely up near the top. Modern games, especially longish ones like MULE have an expectation to have a save feature. Expect to see this feature in the future, as more things progress with MULE Online.
