This was cool! It feels like the art style takes inspiration from early 2000s stickman animations - and I absolutely mean that as a compliment! The walk cycle was clean, and the "freeze" mechanic is a good take on the permanence theme!
I wish the background had a little bit of texture or a gradient - it's a little disorienting when both the player and the platforms are moving.
Congrats on your progress in Godot!
