very very amazing idea! i was literally like "WOW!" the moment i realized whats the game about. it was not so clear at first and i think not only this wouldnt count as a flaw but also its a very cool point to let the player figure out the system and mechanics by themselves, as it gives the feeling of being rewarded somehow.
i loved the concept, it was so original and also valuable. i dont usually play jam games for that long since there are many submissions, but this really hooked me and i actually loved playing it!
very well done mate! ^^
