The game is very nice and good job, especially the artwork! This is very nice an good! Nothing bad about that.
Also the audio is nice, but it would be a cool feature, if the fairy tail creatures make a sound by the spawning, for example the wolf a bad laugh, because he is one from the bad crearures and want to trick little Red Riding Hood. But the music is sweet and it is simple, so I love it.
That's a pity, that the game isn't done, because it would be a very nice one!
The gameplay idea is nice, so I'm excited to see the game, so we all can play it.
About the theme relevance: The theme idea, that I read, is nice, but currently, I can't see it in the game. But it is not bad!
Here is a bug: If I spawn the creatures in different position, the layers are wrong, so creatures, there normaly must be behind the other, are in the front.
Anyway, you did a well job and keep this work!
Best regards
Mudy
