Loved the intro cutscene and the silly srites (are Batthew and Catthew related ?) but I have some issues with the gamelay
First, the theme has little to no impact on the gameplay, I understand the pun and it is funny but the gameplay doesn't feel 100% in theme. It feels disconnected even if obviously this gameplay is a direct result of the pun.
There is also a small issue with the room transition to the last room, it is a downward transition and so we die just before getting to the last room
I also think that the difficulty is not well handeled. The second to last room before the key door section is way harder than any rooms apart from the last one imo. Some room looks way harder than they actually are and the opposite, maybe a bit more playtest could have made the game more balanced. The last room is also an unfair. The start is fine and even fun once you understand how to do it consistently but the ending is sooo hard. It could have been fine if it wasn't that much harder than the rest of the game but I spend half of my playtime on this room alone I think.
Loved the ending bit, was really fun. The game feel is also very nice with subtle details in the flap animation.
Great game, amazing narration but sadly a bit unfair at points in the actual gamelay imo
