I genuinely like the concept, art and overall feel of the game. What I don't like too much is the 'turn based' of it, as it feels nonexistent. Coz what does the AI do? Since it doesn't place hearts. Also I feel like sometimes my heart should have triggered but didn't, but I can empathize with that as I know how tough it can be programming stuff to work perfectly.
More people should try this, really cool idea. Thanks for making it :)
