I love the concept. I'm a sucker for "elemental worlds", specialy when they are kinda liminal like yours. I guess what I want to say, is that I like the vibes on the game.
The hub got me a bit confused. Does it loops on it self verticaly and horizontaly? it's kinda dizzying.
i tired the 4 chraracters. I think I have completed the Shark one, and almost completed the Floaty character one. But Cactus and Tounge felt a bit too clunky. I could not finish them.
On the cactus one, this respawn would keep respawning me below the terrain.
The grinding mechanic felt kinda buggy not gonna lie. Perhaps it would be better if we would just snap to the grind by touching it, tony hawk style.
You are good at creating interesting mechanics that changes the gameplay, so I'm interested in seeing where this will progress.
