This is sooooo cute
I really loved the graphics in this game, the environment is beautiful! And the music is such a nice touch to it. The game works fine, but I felt that the upgrades couldn't deal with the new amounts of slime for every wave. And as someone already said, it was frustrating that you can't help a permanent sad goblin.
Other than that, this feels good to play, I had a lot of fun, keep it up!
