Oh and here’s another recommendation:
It’s not a Castlevania title but in the same ballpark.
Made by Konami and plays like a more accessible Castlevania crossed with Micro Machines style asthetic (small characters in a real house, fight Abominable Snowman in the fridge for example) and has 2 player co-op and is based on the cartoon and toy fad that is: Monster In My Pocket (oooooh matron!)
