I like the hookshot a ton. It felt super good to use. Right now it's really awkward to switch the state and platform. One thing is more checkpoints. Right now you can just do a really hard section and then there's another one with not checkpoint.
I feel overall the difficulty could be heavily lowed at least early on.
I feel like the concepts here have a lot of promise just need so game design.
Some suggesting's: Maybe only two color blocks for early levels.
The bomb thing feels like sometimes it doesn't work mid air. So make it feel more responsive.
This one is and overall difficult curve. It's okay to make the game really easy early on and then go up as you go along. The super hard can stay but should be in the right place in the game like late game content.
