This is quite a solid entry. The game looks good and the music is also ok and they fit together really nicely. The game is also quite fun.
There are a few bugs though, and some things are a little bit weird.
You can't jump on ramps, and sometimes you can't jump at a part (at the base of the segment with platforms that you have to climb, and there are no goats). Also at the part with two columns and a stack of cash, if you go for the money, sometimes you can't climb back because your character collides with a wall and starts going up and down continuously.
Also the main menu was a really great idea, I loved it :) but the menu that appears after you die is a little bit annoying, because after you play you're doing stuff to WASD, and when you die you accidentally do DW and accidentally exit your game. If I were to go with the idea from the first menu, I would have made three platforms on top of each other and you would have to jump to the others, just like in the first menu, something like this.

where 1 is retry, 2 is go to main menu and 3 is to quit the game. If you want to retry, you simply just go right. If you want to retry, you jump on the second platform and go left, and the same for quitting.
I'm not sure if this is really the best solution, but sounds good to me :))
