Very pleasant experience with this unusual mechanic! The level Design has a very great flow : each level felt challenging and not far-stretched at all. I still got stuck sometimes but that was to be expected with such an usual mechanic; thanks for this reset button, not everyone add one!
As other people said, the stickiness of the controls is really annoying.
The "death" sound wasn't good either : Since the character tend to repeat it, it makes it awkwardly sexual. Not with deers, please, not with deers!
