I really enjoyed the style of the game, however, I had an issue where the UI would blend into the game and I couldn't read the numbers very easily. Other than that I liked sending what I assume to be children into the abyss.
It's the colours for me. The text colours are very similar to the game palette so it makes it difficult to read at times. Personally, I try to pick contrasting colours for text in my games to allow for readability.
