Really beautiful game! I really liked the art style and the interpretation of the theme! The music was really good too!
Though I do have some pointers and small critiques I would like the share!
First of, I am not really sure if this is something that game does, but I felt that my mouse cursor was moving a lot faster than it usually does. I don't really know why, but that had as a result me struggling with precisely hitting the buttons, as usually my mouse cursor moves a little slower.
Another problem I had was that I personally didn't fully understood, what I had to do (though that is completely on me as I didn't read the description). It actually took me quite a while to understand that I was supposed to click the numbers from 10 to 1 and not for 1 to 10.
After understanding what I had to do though, I had a lot more fun with the game and I found it really enjoyable. I would like to point out that it was a little difficult for me to understand what I had to do in certain levels (the first time I came across them) which resulted in me losing some runs! (But from a design perspective I totally get it, as I could consider the game a rogue-lite)
Regardless I can see that a ton of work and passion was put into this game! And I have to say that is made for a pretty enjoyable experience! Great job!
