Thanks a lot for a lengthy comment! Yeah I completely agree with your complaints, after seeing my friends trying to beat the game I definitely saw my tutorial's shortcomings (and it was even worse during development lol). Also I actually planned on writing music for the game, even had an idea for an in-game mp3 player, but unfortunately had a time loss cuz of uni and irl stuff.
Once again, thank you, glad you had a good time with my game!
