Thanks!
Yeah I was sort of 50-50 with the font I ended up using, as while I found it aesthetically pleasing, I too had difficulty reading it sometimes.
I tried to balance the towers, but since there was quite a lot on my plate seems like I didn't manage that part well enough.
Upgrades was something I wanted to do, overall UI for "manage contraption" was something I planned initially, but didn't find it essential enough to implement.
Oh and enemy feedback, yeah now that I'm looking back it's kinda silly that the crops etc. have better response to damage than enemies, need to patch that in too.
Thanks for compiling a pretty good list of things to fix!
