Insane game, I love it. Unfortunatly because of limitation, it is impossible to get far (altar is not being regenerated). I managed to get 100 grass and 10 chickens, but then the altar always dies.
Bugs:
After you die the UI at the bottom breaks.
On late waves, when you have a lot of grass and chickens planted + all monsters, the fps drops (maybe because I play in web mode)
Improvements:
Make altar regenerate
Maybe make paths from where the monsters will come (like in Tower Defence)
The game has so much potential, and I have so many ideas for it.
I would love to plant grass on the whole screen to have some haha moments (unfortunatly grass is capped at 100)
