Thanks for playing.
I understand what you are saying. Since it was a Gamjam submission with a restricted time. We thought of just making the first level super easy for players. We had another discussion about the tutorial the way you mentioned as well. If we add that, still players have to figure out the rules of game. So to overcome all this we kept first level easy and added a good and basic tutorial on how to play the game and it's basic of how to.
