I am working on other stuff at the moment, but I will consider your proposal.
Problem is that the STATS bar (that is on the bottom of BBC Micro screen) does not fit to atari screen (PAL). I just realized I have not checked how it behaves on NTSC.
Anyway I have developed dynamic DL/DLI which is showing the STATS bar on the top or at the bottom of screen depends on which tower is currently selected and it is designed in gray shades... so I'm not sure whether it would look good when also the bottom wave stats will be black and white.
I will post some screens here after I get further.
