The music is what makes the Game Epic.
It kinda gives the "you can do it" vibe that makes you want to play the game more every time you fall of a corner. I really liked this game because it was based on a simple concept and built steadily with increased difficulty in its level progression.
I could definitely feel it get harder each level, I think the grey tiles make the ball roll slower than the white tiles that felt very slippery.
This is what i could tell because it felt like it for me, but I am not sure if this is how the game was designed or whether it was my eyes playing games :)
My suggestion would be to change the color of the ball into a Brighter color that contrasts the
background tiles, This would allow for increased attention or better focus when you can differentiate the fore ground from the Back ground making it more appealing to the eye.
I thought the ball looked too transparent for it being the main focus of the game!
Would also appreciate if you could make a difficulty settings for the game with presets like Easy Medium Hard for people to experience the game on a whole.
All people would not appreciate playing the game on medium preset, just because you made it
doesn't mean there cannot be an easier mode- There always is an Easier mode from a 3rd persons point of view!
It is always an 'A' for effort and I really enjoyed the game thoroughly and I really wish you could make better improvements on your next game.
Whoever made the music it's a 5/5 and your choice was on point !
Well done on your game and Good Luck further !
