Yaa! Thank you for your kind words omg! The difficulty is quite high because it is a very much an voice control & generosity education game. Our aim was not just teaching generosity and it's consequences (+ or -) but also having a fun way of teaching singing because it's not readily available to a lot of people.
Yk even my teammate who was developing it, he couldn't get it right HAHAHA (it was easy for me because I'm vocally-trained). So, the game was designed in a way that when the player does get it right, the animals are extremely cute so that they find it worth the effort!
Also side note, this is a demo game with all the notes (even the difficult once's) in one level but if we get a chance to develop it, it'll definitely be spread out across levels to make it more progressive!
