This one's really good! I like the gameplay but it's a little tricky. There's no good indication for when to hit or block, and even what seems like perfect timing often doesn't work. I feel like a system like this needs a lot of refinement, and controls need to be tight. Without clear indicators, it will probably be impossible for players to get it right. I thought there were blocking indicators, but timing with that ring power up often doesn't work for block either. I can usually get the first block to work, but the second block is completely unreliable.
Also, I would play a whole game about Gabbo and Gobbo, no joke.
