I liked the game and its creepy atmosphere, though it reminded me many movies  of dog escaping from its owner to some dangerous place with a monster and then making his owner getting killed by that monster while he was looking for the dog. And the  dog in the end surviving everything.

Also even though at beginning it makes sense, later repeatedly calling for the dog starts reminding me that meme from Hard rain "Press E to Jason!" and it starts to be annoying and unlogical. I doubt that the boy would continue calling his dog while  chased by the Jabberwocky and at same time  dog could keep barking  due being scared.

Also unlike other horror games this makes Jabberwocky easy, as he catches player only with leap attack, it´s easy to escape him and ever if he catches the player, we have plenty of time to escape from his grasp. In fact somebody in one Youtube video even made joke how the Jabberwocky is useful fast travel feature, dragging us through the field :-) . As lore says that he likes to play with his prey like a cat with a mouse, it makes sense, but there could be good some stamina or other limit after which it would be impossible to escape Jabberwocky´s grasp and also when he would  become harder due deciding to stop playing with his pray and finally going after his dinner. Or maybe with difficulty level?

Also I found one wasted potential there - he is mimic and can mimic boy´s voice and I think even the dog´s bark? But he either isn´t chasing protagonist (unless I was too lucky) or when he chases him, he just doesn´t use the mimicking ability much. I would more like when boy calls after his dog, both Jabberwocky and dog would respond to his call (or one of them) and player would have to guess which bark/voice is right. If player could run to wrong bark/voice and instead encounter Jabberwocky, it then could mimic player to taunt him and either chase or catch him instantly. And after escaping him hiding somewhere again.

Also I was suprised by one thing - there was intro cutscene, but no ending one? Even though we achieve our goal - find the dog and escape with him out, there would be still nice some cutscene. And also in certain sense of humour the easiest way to find the dog is  to let Jabberwocky catch us, because we will find our dog that way too, only shame is that the protagonist doesn´t survive that.

EDIT: I checked it out and it takes up to 18 seconds  after Jabberwocky catches the player before he decides to eat him. I think as we can break free very easily, up to 5 or 10 seconds could be better. Or make it that each time Jabberwocky catches the player, player would have less time to break free, due protagonist freaking out and Jabberwocky leaving his "playful" mood.

EDIT2: Actually Jabberwock tries to drag you to its lair when caught, so the time how much you have to free yourself depends on far you are from its lair. But it´s still usually plenty of time unless you stand next to his lair, then it´s almost instant game over.
