Hey, I remember your game from DD43. Your art has improved.
Here's a video of me playing (no commentary)

link expires in 3 days. I hope you get to see it.
It looked like the villager spawner was stopping at times until I hovered over the bar. I am not sure if you will see it in the video.
The upgrades are really weak. I would also like to see some indicator showing that the unit was upgraded. Either change in color, or maybe a little star above them, anything would be better than nothing.
I don't know if getting to wave 9 is good, but it felt good to me.
Maybe have some breathing rooms between waves, with some building upgrades, maybe allow me to rearrange my units.
Knights are not tanky enough, and I cannot really replace them when monsters are already stepping on them.
I look forward to your next DD. It was a nice surprise to see you back.
