I really love the attention to detail in things like the sound (and slight animation) of jumping on the garbage can lids. Or how the enemy cats pile up in the starting area as you defeat them. Or how the game's logo causes the cat to have a jump scare. :D
Jumping around feels very good. Combat I found difficult after the first cat. The orange one gave me a ton of trouble until I discovered the key is to wait for your opponent to come to you. Having regenerating hearts as a sort of 'stamina' system is a nice touch, where it's not about how much you swipe your opponent all that matters is being the last (cat) standing. Oddly, the final cat defeated me in our battle, but when I returned they weren't interested in another round and let me pass through.
It's not always obvious where to head to next from one screen to another, but given the options are always up, left or right it's not too much of an issue. :)
