Jumping over the pipe is impossible.
Nice try, but make the controls more like Bit trip runner (http://www.nintendo.com/games/detail/ehwF-vVRQN9Co_aKbzshJm8kBH38Bmei
). The duck last less then 1/4 of a second. No Bueno.
Very hard to find the good timing, and nothing makes me want to take time to actually find it : graphics are uninspired 8-bit (Ash jumping over Mario pipes... yeah, thanks a lot), and retro-sounding MIDI covers of metal songs are NOT good video game music.
The duck does not last long enough when compared to the jump .Makes the two controls feel very unbalanced, and makes timing hard. I also suggest making controls customizable. Neat, and fun little game though.
