I have put together a full list of the current progress of Energy Tycoon and what will be needed to move onto the next step of development, which would be getting it into the hands of testers like you!
Green = complete enough for next stage
Orange = work in progress
Red = not started
Plant Operations / Mini Games
Graphical Needs & Misc
I estimate that the main systems along with 80% of the mini games will be complete by the end of August. The graphical needs and misc list will be done during the revamp.
Once all of these become green, you will be able to test and download the game from the android play store.
At the moment open beta begins, the primary focus is to revamp the game graphically so everything flows well from any point in the game. The total length of that process will depend once it gets to that stage.
After the revamp is done and feedback is good from the testers, I will end the beta and fully open up the game for everyone.
