Pretty good, just few things I didn't like still were the lack of English subtitles (at least I couldn't find it on APK), is the player one of the kids? Is it a parent? The rabbit?
The footsteps and jump sounds, not echoing and the same everywhere, moving in the vent don't go "clong clong"
you need to jump to actually climb the ladder in game, maybe a small animation would be better, and the game lacks save points, closing the game does not offer a "continue" or "resume" and it feels like some props could be turned into simple textures effects to save memory and prevent the glitch I saw where standing on it forces repeated jumps
Finally the monster scene : I liked the idea of collecting batteries by doing tasks but the map was a bit too small for the tasks, just moving the ball takes enough time for the monster to do a full loop of the map, the 10 seconds cooldown upon death also was.... not very great for a noob like me who died every 5 seconds. And with that the monster could also have a few better points : maybe footsteps that can be heard and give the location of the creature and replacing the music by pure heartbeat (could also be a terrible thing).
But the game was pretty good for a part 1, loved the ambiance and visuals.
