First of all i would really like a settings menu for small things like turning off music or sound.
For me it isnt really relaxing music.
Although i think its alright if you play it on your smartphone i dont think its alright for clicking with a mouse.
Maybe change the colors into keys on your keyboard for computer users?
I do not see any challenge in it. I don't reach any level or goal. It doesnt go any faster and the only progress i make is with collecting those figures.
I hope you don't take this review too negatively.
Overall i give 3 stars becouse i do like the idea! :)
