I understand you are busy with Mars One and Raiders at the moment, but when the time comes and these projects are complete, I would like to see Mars Colony Frontier finished.
There are a couple of bugs that make the game have major problems and unplayable. Luckily the player can work around these.
Bugs:
1. Upgrading base modules then exiting the game will cause them to move at random with in the build site making the base incomplete.
2. using the transport NPC to go to your base will cause a glitch that removes the atmosphere from the inside the base.
I understand you have a limited budget and time, but you posted on Facebook a while back that you wanted to update Mars Colony Challenger and Frontier to he new game engine with better graphics. For saving money, I would suggest updating only challenger, because the graphics are not as good as the new ones on Frontier and Mars One.
Thanks for clarifying the timeline.
