I like the classic 8-bit RPG elements, and noticed that used the Pokémon damage received SFX and recreated the water gym from one of the game boy games. That was funny and interesting, but a bit immersion-breaking.
The kill animation was very cool and stylistic. I was frustrated with the opening text-based exposition. I think occasionally changing the on screen image(s), or adding some kind of movement or SFX could buy time until the player loses patience or loses concentration.
Once the game got going, I felt curiosity about what could be hidden in the area, I feel that the use of a flashlight helped with that sensation.
It was cool that you had stuff like a car, garden and guillotine, it really added to sense of place and variety. I, personally, would've like more interactive elements, to be able to affect things in some way, even if it was like gimmicky stuff like dropping the guillotine.
