Wow! Thank you so much for your comment!
The map had to be cut from the game last-minute due to some errors when building, but we didn't change the tutorial text in-game to reflect that :( Our apologies for the confusion!
Technically, at the end of the game you can go back to the menu by pressing Esc ;D But yeah, the ending of the game was definitely not focused on since this is just a vertical slice, so we wanted to prioritize the gameplay itself. We're also aware of the bubbles not being able to be picked up when they hit the ground, it's indeed a collider issue ^^
Some of the dev team indeed agrees that the hookshot is OP, others say that it's supposed to be that way. It'll be something that we'll discuss internally...for a long time probably xD
Thank you again for your lovely feedback and for playing our game!
