The gameplay is nice, easy to understand and hard to master it, You can fall adict very easily haha
But I take a time to figure that you lose when the gun hits a rock, because sometimes I landed into one and nothing happend, but others i hit and die. I think saying it in some place or add a visual in the gun when you hit could work.
And my personal take, this REALLY needs some music in the gameplay, a nice grove that make me move in my seat and BOOM I'll fall playing this for an hour or two.
