I added the records menu as a meme, but players being able to choose what music they would like to listen to is a nice idea.
I hadn't thought of strafing yet, but that is also a good suggestion.
The towers are only in the demo to have any kind of gameplay. I didn't really have time to create engaging enemy encounters under an afternoon.
The user interface definitely needs some work, and I will remember to consider contrast.
Thanks for taking time to play with the demos, I really appreciate it and I'm sure the others do too.
