Cool! That sounds like a doable timeline for programming ... which is a lotta work after all (and I hope if you use any A.I. tools to help you, make sure to review them for sloppy Code, since that seems to be quite a problem with those still, even though it has gotten better with tools, that also can find severe bugs, that could be used as backdoors - and not the pleasant kind ;-P ).
Thanks for the transparency and don't let anyone rush you - I've always hated Tower Defense Games, but yours is the first I don't and in parts even "came" to love ;-P <3
So, keep up the awesome work, folks - love whatcha doing!
