There isn't an indicator/pointer showing which option the player is picking during the dialogue segments.
Subjective but i think the camera going up and down when jumping is kinda disorienting.(it seems to not do that anymore in the later stages)
The main mechanic of the revovler knockback is a complicated one.
The first impression is that it also boosts my speed/ add speed to my momentum like the slide ,but actually it only gives the player a recoil kick in horizontal/vertical,so you cant do things like getting a bigger jump from jumping and firing at the same time.
So far from the level design it feels more like a 6 limit double jump,which means that if you fire it before reaching the apex of the first jump,it overrides it with a fixed pushback.
Level 10 is a showcase of that which if you dont fire the revovler directly downwards, you dont get enough upward recoil to go up.
The AI is probably his wife.

also on a second playthrough the model doesnt revert back to the old one without a gun until a death.
