Heyo! Thanks for commenting.
That's a fair critique, I think it'd be great to add more critters in a future update.
I played this game on day one and just now realized I'd forgotten to rate it and comment.
There are so many things to love here, from the theming and message to the variety of mechanics you included. I reckon it's a slam dunk. I love 2.5D stuff and thought this is a great example of it done right.
Kudos to the team!
