Quite a fun game, the controls feels great and the ambiance is nice.
Loved that there are some secrets here an there, could be great to place some optional collectables in some of those places .
Although the final boss I felt like it was a bit of an overkill, I can see it being enjoyed by some players.
It might be more of a personal opinion, but at the boss fight, I think I have died a few times form the day/night transition while in the bat for. It might help to have it a bit more telegraph. Like to wait to have the transition completed before applying damage. Or have a video/audio cue just before the transition.
