Tried the game at your updated link: https://finnfert.itch.io/tiki-trail-web
This is a well-crafted game. It's clear a lot of work went into it. It looks a great and has nice details like the crossing island scene and voice acting :)
My main gripe is that you made a really beautiful looking game but you cover most of it up with the mask. I think you are trying to put some tradeoffs for the player. But the vibe I get from this game is cozy and I wouldn't mind pressing a button to toggle these abilities while I keep my field of view and enjoy the scenery. Maybe reduce the alpha of the black significantly so that you can still have the unique look of your mask while letting people enjoy your nice looking game.
