Hey Mariana, thanks for your feedback.
It was one of our goal, to make a one-button game that has depth. The risk with depth is that you can become complex, the balance is not easy to find and different people will have different feelings about it :o
Could you tell me what part was too complex for you? I'm genuinely interested to know to see if I could tweak/change that (or propose options / game mode).
Cheers
