Nice simple game especially the Ivy's action development ;).
Also some sound effect and music would be nice too. You can get some for free in open game art.
Also about the red notification box. Make it transparent (except the text)so when Ivy goes left, you can still see what happened behind ;).
Btw, when sprinting and jump far right, Ivy passed through the wall. Have you set the object solid? I got passing through issue too when not setting object solid when colliding on object (I was GM user too long ago).
