I absolutely loved this! I enjoyed discovering how each gameplay mode worked, and training my brain to think in a way that worked with the game's radial controls.
On my first attempts, I was only managing a couple of points, but after working through and trying each mode, I was comfortably able to get up over 40 points in the first mode.
I really appreciated how the background colour responds to your current state in a way that increases the anticipation of the things you want to collect and heightens the surprise of hazards when you're "healthy," but also heightens tension by making the red bricks less readable when you're in "damaged" mode.
The minimalist style and presentation in general feel really strong, and I though the "shatter" effect on death worked really well.
It's always nice to revisit and give life to an old idea. I'm glad to read that you were able to realise this early concept into such a solid experience. Well done!
Hope you had a positive experience using Godot, and thanks for doing a Linux build :)
