Thank you for the feedback and support. Much appreciated!
A large part im currently working on is making everything a bit more user friendly. So you are correct, at the main base you can interact with the systems, which allow you to buy food and water. The current implementation allows you to earn points by completing objectives, as well as keeping all the towers on for a significant time period.
Also the next update due for release soon should have a much nicer pixelation effect. (The filter effect currently is a super low render scale to help performance instead of just a filter overlay)
Always open to any ideas for the future !
Thanks again for the comment
