★★★★★person who touched grass· Dec 16, 2022
The game is really good! On the trailer it seemed hard to me when I started playing it was a bit of a challenge, but it was really fun! Anyways I gave 5 points because it's a good game (with a good story) and for the prize I got Edit: also mentioning the fact that ads don't come up that much, which is very rare for a mobile game

Great game but the music turns itself back on every time you die, so I can't listen to my podcasts while playing :(Edit (v.57): Dev fixed the bugs! Much appreciated

Best platformer I've played all year, and that's saying something since I'm a very vigorous gamer. Love it, keep up the good work dude

"I'm so sorry for doing this :(" shut up. You suck.
★☆☆☆☆Patrik Pocsik· Feb 4, 2026
In short:it sucks. Expanded:it is not hard, it is not horror, it had potential, its full of ads, pay walls, ad walls, and way to edgy and meaningless.
★☆☆☆☆Devesh Parekh· Feb 1, 2023
Paid game has ads and in-app purchases.
