Good game, I like the music and art
I can't use right shift to dash, it doesn't work. And you know, in browsers ctrl+w is close the window. Try it. You can't complete the game without it.
Edit: I can use arrow to jump, so I have completed the game. This lines are up to something
And sounds a bit noisy and annoying
But overall it's nice
Edit 2: next time make your game less bit, I had to zoom out the page to play
