Cool game! Fun mechanics and a decent artstyle!
If i were to complain...
Probably the biggest one: i can't tell if this is an endless runner or not, if it isn't, i didn't finish it. There isn't anything that marks your progress (log technically does but it's not obvious) so i wasn't really compelled to keep progressing. If it IS an endless runner, there isn't anything that marks your score, so i wasn't compelled to try again.
There is no actual incentive to go forward on your screen, i mostly stayed at the bottom
The logs are bigger than the stones yet i can't jump over the stones but i can jump over the logs.
