I have played this game many times, but I've yet to no-hit it. I've managed to get a run with just 2 hits, but the last stage is particularly difficult as this imps appear to spawn in a completely random pattern, and there don't seem to be observable rules as to what causes an imp to bounce or not, meaning you have to treat every imp as though it could potentially bounce.
I'll keep coming back to it regularly to see if I can eventually no-hit it. I'll post an imgr link or something when I do.
