Awesome, I will keep an eye on your releases!
I will restrain my stream of thoughts, let me just say that just from purely practical side: sitting through 20 waves at your First acquaintance with the game seems to be a high barrier. Player will get a real feedback on their actions only by the end. Of course, you shouldn't explain your whole vision to me, you have reasons, I just think there's a problem to be addressed. Good luck! ;)
