Oh I finished the game allright, with like 50 death.
The thing is that hitbox of the flames when they drop are larger than the sprite by a few pixel, which isn't much really, but can really screw you over when there is everything going on.
I don't mind big hitbox, but when it's not in sinc with the sprite it thows me off because I can't really know how close I can get of them.
The game was fun still and I'm not complaining.
