First of all, thanks for the feedback! Yeah, we would have definitely liked to make the sounds ourselfs, but because we are new to this we wanted to focus on what we knew. About the jumping, it was kind of intentional to make it hard, but i agree is weird that it "feels" that it speeds up, don't really know how to solve that, may look into that in the future. For the theme, we made it that the less you press the jump button, the more you jump. Again, thanks for playing and giving us feedback!
